Latin I

The big picture

Welcome to Latin. Before grammar, we learn how the language sounds. Scholars have reconstructed the classical pronunciation, roughly how an educated Roman spoke in the age of Cicero and Caesar, around the first century BC. The good news is that Latin spelling is far more regular than English. Almost every letter has one sound, and words are pronounced the way they are written.

Key idea: learn the sound rules once, and you can read almost any Latin word aloud on sight, long before you know what it means. Good pronunciation also trains your ear to hear the word endings that carry Latin grammar.

The alphabet

The classical Latin alphabet has 23 letters. It lacks j and w entirely, and the letters i and u do double duty as both vowels and consonants. The letters y and z appear almost only in words borrowed from Greek.

Letters	Note
A B C D E F G H I K L M N O P Q R S T V X Y Z	23 letters; no J or W
i	vowel (as in vinum) or consonant "y" (as in iam)
v	the vowel u and the consonant v were one letter, V

When you see Julius in an English book, a Roman carved IVLIVS: the same name through different spelling habits. Modern textbooks print u and v, and i for both vowel and consonant i, which is the convention this course follows.

The five vowels

Each Latin vowel has a short and a long value. Length is real and can change meaning. Textbooks mark a long vowel with a macron, a bar written over it, as in a versus ā.

Vowel	Short sound	Long sound
a / ā	like the a in "cup"	like the a in "father"
e / ē	like the e in "pet"	like the ey in "they"
i / ī	like the i in "sit"	like the ee in "see"
o / ō	like the o in "hot"	like the o in "note"
u / ū	like the u in "put"	like the oo in "food"

Length is not decoration: it can be the only difference between words and between grammatical forms. Classical examples include liber ("book") next to līber ("free"), and malum ("evil") next to mālum ("apple"). Soon you will meet a grammatical pair: puella with short -a is a subject, while puellā with long -ā means "by or with the girl". Your ear can learn this distinction the way it learns a musical rhythm: long vowels simply take about twice as long to say.

Diphthongs

A diphthong is two vowels blended into one syllable. Learn the three common ones and a couple of rarer ones, and no vowel cluster will surprise you.

Diphthong	Sounds like	Example
ae	"eye" in "bye"	Caesar begins "kai"
au	"ow" in "how"	aurum ("gold")
oe	"oy" in "boy"	poena ("penalty")
ei, eu, ui	each vowel glides quickly into the next	deinde, heu, cui

A diphthong always counts as long for the syllable rules below. And when two vowels sit together but do not form one of these pairs, say them separately: poēta is three syllables, po-E-ta, and deus ("god") is DE-us.

Consonants that differ from English

Most consonants match English, but a handful are critical and worth drilling first.

• c is always hard, like English "k", never soft. Cicero was pronounced "KIH-keh-roh", and civis ("citizen") begins "kee".
• g is always hard, as in "go", never as in "gem".
• v is pronounced like English "w". So vivo ("I live") sounds like "WEE-woh", and veni, vidi, vici begins "WAY-nee".
• i before a vowel at the start of a word acts as a consonant and sounds like English "y". iam ("now") sounds like "yam".
• r is trilled or tapped with the tongue, as in Spanish or Italian.
• s is always the hissing "s" of "sit", never the "z" of "rose".
• t is always a clean "t"; the group ti never softens to "sh" as it does in English "nation".

Three more combinations complete the set. qu sounds like "kw", so aqua is "AH-kwa" and equus ("horse") is "EH-kwus". x is "ks", as in rex ("king"), "reks". The pairs ph, th, and ch appear in Greek borrowings such as philosophia and were said as breathy p, t, and k; pronouncing ph like English "f" is a fine approximation for a beginner. Every consonant is pronounced; Latin has no silent letters, and doubled consonants are held longer, so annus ("year") keeps both n's audible, distinguishing it from anus.

Syllables and stress

Latin words are stressed by a simple rule. In a word of two syllables, stress the first. In longer words, look at the second-to-last syllable, called the penult. Stress the penult if it is heavy, meaning it holds a long vowel, a diphthong, or ends in a consonant. Otherwise the stress falls back to the third-to-last syllable.

So amicus ("friend") is stressed a-MEE-cus, because its penult has a long i. But femina ("woman") is stressed FEH-mih-na, because its penult is light. The teacher word magister is ma-GIS-ter, since its penult ends in a consonant.

To find the syllables in the first place: every vowel or diphthong makes one syllable. A single consonant between vowels starts the next syllable (fe-mi-na), while two consonants usually split between syllables (ma-gis-ter). Work through a new word in that order, divide, weigh the penult, place the stress, and you will pronounce it like a Roman.

How to build it: sounding out a new word

Take Caesarem, a form of Caesar's name you will meet when he is the object of a sentence. Step 1, scan for diphthongs: ae is one, pronounced "eye". Step 2, divide the syllables: Cae-sa-rem, three of them. Step 3, weigh the penult, -sa-: its a is short, and the syllable ends in a vowel, so it is light. Step 4, stress therefore retreats to the third-from-last: KAI-sa-rem. Step 5, apply the consonant rules: hard c, hissing s. Done: "KAI-sa-rem". Every Latin word yields to this same five-step routine.

Vocabulary to sound out

Latin	English	Spoken hint
amīcus	friend	a-MEE-kus
fēmina	woman	FAY-mih-na
vīnum	wine	WEE-num
aqua	water	AH-kwa
poēta	poet	po-AY-ta
rēgīna	queen	ray-GEE-na
equus	horse	EH-kwus
via	road	WIH-a

Example sentences

Read each aloud, pronouncing every letter, then check the English.

• Poeta puellam amat. comes out "po-EH-ta pu-EL-lam A-mat" and means "The poet loves the girl."
• Vīnum bonum est. "WEE-num BO-num est" means "The wine is good."
• Caesar in Galliā est. "KAI-sar in GAL-lee-a est" means "Caesar is in Gaul."

Reading: a first passage

Here is a short adapted passage. Sound out every word, then read the translation.

Rōma in Italiā est. Rōma antīqua et clāra est. Poēta in viā ambulat. Fēmina aquam portat. Amīcus meus est agricola.

Translation: "Rome is in Italy. Rome is ancient and famous. A poet walks in the road. A woman carries water. My friend is a farmer." Notice there are no silent letters, and the c of clāra is a hard "k".

Three things to hear as you read. First, every final vowel is fully pronounced: antīqua ends in a clear "kwa". Second, the long marks on viā and Italiā are grammar at work, the "in the road / in Italy" ending you will study soon; say them long. Third, the words est and et are as short as they look; Latin never pads a syllable.

Two pronunciations, one language

The classical system in this lesson is not the only tradition. Ecclesiastical pronunciation, the Latin of the Roman Catholic Church and of choral music, developed centuries later under Italian influence: there v sounds like English v, c before e or i softens to "ch" (so caelum, "heaven", begins "cheh"), and ae becomes a plain "eh". Neither system is wrong; they belong to different eras. This course uses the reconstructed classical sounds because our authors are Cicero, Caesar, and Vergil, but if you sing in a choir or hear legal and medical Latin in English courtrooms and clinics, you are hearing the later traditions.

Common misconceptions

• c and g go soft before e and i. They do not. Classical c and g are always hard, so Cicero starts like "kee" and gigno like "gig".
• v sounds like English v. In the classical sound it is English "w"; vivo is "WEE-woh".
• Latin has the letters j and w. It does not. The consonant "y" sound is written with i, as in iam.
• A macron is a stress or accent mark. It only marks vowel length. Stress follows the penult rule, which is separate.
• ae is said like "ay". It is said like "eye", so Caesar begins "kai".
• The Romans wrote macrons. They did not; macrons are a modern teaching aid. Inscriptions occasionally marked length with an apex mark or a tall I, but ordinary writing left length for the reader's ear.
• Church Latin is a mistake. It is a later, historically genuine tradition; classical and ecclesiastical pronunciation simply serve different repertoires.

Recap

• Latin uses a 23-letter alphabet with no j or w; classical pronunciation is highly regular.
• Every vowel is short or long, and a macron marks the long value; length can distinguish words and grammatical forms.
• c and g are always hard, v sounds like "w", consonantal i sounds like "y", qu is "kw", and s always hisses.
• The diphthongs are ae ("eye"), au ("ow"), and oe ("oy"), and a diphthong counts as long.
• Divide syllables, weigh the penult, then stress: heavy penult takes the stress, light penult passes it back.
• Classical pronunciation suits Cicero and Caesar; the church's later pronunciation suits sacred music.

The big picture

English is mostly a word-order language. Compare "The dog bites the man" with "The man bites the dog." The words are identical; only their order tells you who bites whom. Move the words and you change the meaning.

Latin works differently. Latin is an inflected language: it signals a word's job by changing the word's ending, not its position. This process of changing endings is called inflection. Because the ending carries the grammar, Latin can move words around freely for emphasis without confusing the meaning.

A first example

Take the Latin words for "girl" (puella), "loves" (amat), and "poet" (poeta). Watch what the endings do:

Latin	Meaning	Who does what
Puella poetam amat.	The girl loves the poet.	puella = subject, poetam = object
Poeta puellam amat.	The poet loves the girl.	poeta = subject, puellam = object

The ending -a marks the subject, the doer, while the ending -am marks the direct object, the one acted on. The English translation depends entirely on the endings, not on which word comes first.

English has a little inflection too

You already use inflection every day, just in small doses, and seeing where English keeps it makes Latin feel familiar rather than alien.

English remnant	What it marks	Latin equivalent idea
he / him / his	subject / object / possessor	exactly the jobs Latin endings mark on every noun
who / whom / whose	subject / object / possessor	same three roles again
the girl's rose	possession with 's	rosa puellae
walk / walks / walked	person and tense on the verb	Latin verb endings, which go much further

English can no more say "Him bites the dog" and mean the dog was bitten than Latin can confuse puella with puellam. The difference is quantity: English inflects a handful of pronouns; Latin inflects every noun, adjective, and verb.

Stem and ending

A Latin word is built from two pieces. The stem carries the core meaning, so puell- means "girl". The ending carries the grammar, so -a signals subject, -am signals object, and -ae signals "of the girl".

Thus puella is puell- plus -a. When you learn a Latin word, you really learn its stem plus a whole family of endings. Memorizing those endings is the heart of Latin, and it is very doable, because the same endings repeat across thousands of words.

One noun, five jobs

To feel inflection at work, look at how a single noun reshapes itself to play different roles in a sentence. Each ending answers a different grammatical question. The formal names in the first column belong to the cases, which the next lesson studies one by one; meet them here as labels on jobs you already understand.

Case name	Form	Ending	Job	English
nominative	puella	-a	subject	the girl (does something)
genitive	puellae	-ae	possessor	of the girl
dative	puellae	-ae	recipient	to or for the girl
accusative	puellam	-am	object	the girl (acted on)
ablative	puellā	-ā	means or place	by, with, or from the girl

One stem, five endings, five different jobs. English would need extra words such as "of", "to", or "with" to do the same work that a Latin ending does by itself. Notice too that puellae serves two jobs at once, possessor and recipient. When a form is shared, the rest of the sentence tells you which meaning applies. And see how the ablative differs from the nominative only by vowel length, short -a against long -ā: the macron from Lesson 1 is carrying real grammar.

Why this matters for reading

Once you accept that endings, not order, carry the grammar, Latin stops being mysterious. Your task as a reader changes. Instead of trusting the sequence of words, you inspect each word's ending, decide its role, and only then assemble the meaning.

This is a different mental habit from reading English, and it becomes natural with practice. The two most common families of endings, called the first and second declensions, are the subject of the next lessons. Master those, and the endings above will feel automatic rather than mysterious.

Vocabulary: how the dictionary lists a noun

A Latin dictionary lists a noun by two forms plus its gender, for example puella, puellae, f. The second form is the possessive, or genitive, and it reveals the stem and the noun's family.

Dictionary entry	Meaning	Gender
puella, puellae	girl	feminine
poeta, poetae	poet	masculine
nauta, nautae	sailor	masculine
agricola, agricolae	farmer	masculine
rosa, rosae	rose	feminine

How to build it: your first Latin sentence

Translate "The sailor gives a rose to the girl." Work role by role, the way a Roman writer did. The giver, the subject, is the sailor: nominative nauta. The thing given, the direct object, is the rose: accusative rosam. The receiver takes the dative, "to the girl": puellae. The verb "gives" is dat, and Latin likes its verb at the end. Assemble: Nauta puellae rosam dat. Now the striking part: scramble it to Rosam nauta puellae dat or Puellae rosam dat nauta and the meaning stays exactly the same, because each word carries its role on its back. Only the emphasis shifts, leaning on whichever word comes first.

Example sentences

The verb laudat means "praises". Watch the endings decide the meaning.

• Nauta poetam laudat. means "The sailor praises the poet." The ending on nauta makes it the subject.
• Poeta nautam laudat. means "The poet praises the sailor." The roles have swapped, marked only by the endings.
• Puellae rosam agricola dat. means "The farmer gives a rose to the girl." Here puellae is the recipient.
• Rosa puellae pulchra est. means "The girl's rose is beautiful." Here puellae is the possessor, "of the girl".

The same form, puellae, meant "to the girl" in one sentence and "of the girl" in the next. Only the surrounding words settle which sense is right, and reading Latin well means weighing those clues.

Reading: word order is free

Because the endings hold the grammar, a Roman could write the same idea in several orders. All three of these mean the same thing.

Agricola rosam portat. Rosam agricola portat. Portat agricola rosam.

Translation, in every case: "The farmer carries the rose." The word agricola stays the subject and rosam stays the object no matter where they sit, because the endings never change.

Freedom is not randomness, though. Neutral Latin prose tends to run subject first and verb last, with everything else between. Departures from that default are deliberate: the first and last slots of a sentence are the spotlight positions, so Rosam agricola portat quietly stresses that it is a rose he carries. You will feel this rhythm grow familiar as you read.

Reading: a second passage

Every word here uses vocabulary and endings from this lesson and Lesson 1. Read it aloud, working ending by ending, then check the translation.

Agricola aquam portat. Nauta viam laudat. Poēta puellae rosam dat. Puella poētam amat. Fēmina agricolae aquam dat.

Translation: "The farmer carries water. The sailor praises the road. The poet gives the girl a rose. The girl loves the poet. The woman gives the farmer water." Three notes. In the third sentence puellae must be "to the girl", not "of the girl", because giving needs a receiver. In the last sentence agricolae plays the same recipient role for the farmer. And every sentence parks its verb at the end, the neutral Latin habit.

Common misconceptions

• Word order carries no information in Latin. It still signals emphasis and style; it just does not decide who is subject or object.
• English has no inflection at all. It keeps a little: "he" versus "him", and the possessive "'s". Latin simply does far more of it.
• The endings are random and must be guessed. They are systematic and repeat across whole declensions, so a small set covers thousands of nouns.
• One Latin word equals one English word. A single ending can be worth an English "of", "to", or "with", so one Latin word may need several English words.
• You can skim past the endings and rely on order, as in English. That habit produces exactly backwards translations, "the man bites the dog". The ending is the first thing to read, not the last.

Recap

• Latin is inflected: endings, not position, show each word's grammatical role.
• A noun is a stem plus an ending, as in puell- plus -a.
• The ending answers a question: subject, possessor, recipient, object, or means and place, and these jobs bear the case names nominative, genitive, dative, accusative, and ablative.
• Dictionaries list a noun by its base form, its genitive, and its gender.
• Because endings carry meaning, Latin word order is flexible; neutral prose runs subject first and verb last, and the edges of the sentence carry emphasis.

The big picture

A case is the form a noun takes to show its job in the sentence. Latin has five cases you must master, plus a rare sixth, the vocative, used for direct address. Learn the five as a set: their names, and the one core question each answers.

Cases are the payoff of an inflected language. Where English adds little words like "of", "to", or "with", Latin changes the noun's ending. Once you can name a noun's case, you know its role, no matter where it sits in the sentence.

The five cases

Case	Core use	English clue	Example (English)
Nominative	Subject of the verb	who or what does it	The girl loves.
Genitive	Possession	of, apostrophe-s	the book of the girl
Dative	Indirect object	to or for a recipient	I give a rose to the girl
Accusative	Direct object	the thing acted on	I see the girl
Ablative	by, with, from, in	means, place, source	I write with a pen

How to think about each case

• Nominative is the doer. Ask "who or what performs the verb?" That word is nominative.
• Genitive is the possessor. It usually translates with "of" or an apostrophe-s. "The queen's daughter" equals "the daughter of the queen".
• Dative is the recipient. Ask "to whom or for whom?" In "I give the boy a coin", the boy is dative.
• Accusative is the direct object. Ask "the verb acts on whom or what?" In "I praise the sailor", the sailor is accusative.
• Ablative is the most flexible case, covering "by, with, from, in". It handles the means, the source, and often the place where something happens.

The ablative deserves one more minute, because it bundles three ideas a beginner should keep separate. Means: the tool something is done with, no preposition needed in Latin (aquā, "with water"). Accompaniment: the person you do it with, marked by the preposition cum (cum puellā, "with the girl"). Place where: the location, marked by in (in vīllā, "in the country house"). If you ask "with what tool?", "with whom?", or "where?", the answer sits in the ablative.

One special job of the nominative

The nominative has a second duty beyond naming the doer. After a linking verb, above all est ("is") and sunt ("are"), the word on both sides stays nominative, because the verb works like an equals sign rather than an action: Iūlia est puella. "Julia is a girl." Nothing is acted on, so nothing goes accusative. Grammarians call the second nominative a predicate nominative. English speakers often want to make "girl" an object here; resist the urge, and let est balance two nominatives like a scale.

The rare sixth case: the vocative

The vocative is used only for calling or addressing someone directly, as in "Marcus, come here!" For almost every noun the vocative looks exactly like the nominative, so it costs you nothing extra to learn.

The one exception is the second declension masculine in -us, which shifts to -e in address. So amicus ("friend") becomes amice when you speak to a friend, and dominus ("master") becomes domine. You will meet this again with the second declension.

Seeing the cases in Latin

Here is one noun, puella, shown in each case. The exact endings are the subject of the next lessons; for now, watch how the ending signals the role.

Case	Latin sentence	English
Nominative	Puella cantat.	The girl sings.
Genitive	Rosa puellae pulchra est.	The girl's rose is beautiful.
Dative	Agricola puellae rosam dat.	The farmer gives a rose to the girl.
Accusative	Puellam videō.	I see the girl.
Ablative	Agricola cum puellā ambulat.	The farmer walks with the girl.

Look down the endings: -a, -ae, -ae, -am, -ā. Five small changes, five different jobs, all on the one word "girl". The genitive and dative even share the ending -ae, so the rest of the sentence must tell them apart, a pattern you will meet often.

How to build it: mapping an English sentence onto cases

Before you can write Latin, you must be able to read an English sentence the Roman way. Take "The queen gives the girl's rose to the farmer in the garden." Interrogate each noun. Who performs the giving? The queen: nominative. What is given? The rose: accusative. Whose rose? The girl's: genitive. To whom? The farmer: dative. Where? In the garden: ablative with in. Now the whole sentence is a case map, queen-NOM, rose-ACC, girl-GEN, farmer-DAT, garden-ABL, and the Latin almost writes itself once you know the endings: Rēgīna rosam puellae agricolae in hortō dat. Run this five-question drill on English sentences you meet during the day; it is the single best preparation for the declension lessons ahead.

Number and gender

Every Latin noun also has a number, singular or plural, and a gender, masculine, feminine, or neuter. Gender in Latin is a grammatical category, not always tied to biological sex.

So puella ("girl") is feminine, agricola ("farmer") is masculine, and bellum ("war") is neuter. You simply learn each noun's gender along with the word. Gender matters because adjectives must match their nouns, as you will see later.

Vocabulary

The genitive in each entry is the dictionary's way of showing you the stem, as Lesson 2 explained. The last three words appear in the reading below.

Latin (nom., gen.)	English	Gender
puella, puellae	girl	feminine
agricola, agricolae	farmer	masculine
rēgīna, rēgīnae	queen	feminine
bellum, bellī	war	neuter
patria, patriae	homeland	feminine
fīlia, fīliae	daughter	feminine
vīlla, vīllae	country house	feminine
hortus, hortī	garden	masculine

Reading: Julia the Roman girl

Read the passage, then check the translation and the case notes.

Iūlia est puella Rōmāna. Iūlia in vīllā habitat. Amīca Iūliae est Cornēlia. Puellae in hortō ambulant.

Translation: "Julia is a Roman girl. Julia lives in a country house. Julia's friend is Cornelia. The girls walk in the garden." Here Iūlia is nominative, Iūliae is genitive ("of Julia"), and vīllā and hortō are ablatives after "in".

Three comprehension notes. In the first sentence puella stays nominative after est, the predicate nominative at work: Julia and girl are the same person, so both sit in the subject case. In the last sentence puellae is not "of the girl" this time but the nominative plural, "the girls", and the verb ambulant ("they walk") confirms it; the same letters can belong to different slots, and the verb is your referee. And hortō shows the second declension's ablative in long -ō, a preview of Lesson 5.

The payoff

Once you can spot which case a noun is in, you can decode a Latin sentence whatever the word order. A nominative is your subject; an accusative is your object; a dative is a recipient; a genitive is a possessor; an ablative usually needs "by, with, from, or in".

Keep this five-case map in your head as a checklist. When you read, name each noun's case first and its role follows at once. The next lessons give you the actual endings that produce these cases, starting with the first declension.

Common misconceptions

• Grammatical gender always matches biological sex. It does not. agricola ("farmer") is masculine but ends like a feminine noun, and bellum ("war") is neuter.
• The ablative has a single meaning. It is the workhorse case, covering means, source, accompaniment, and place, so its translation depends on context.
• After est, the second noun is an object, so it goes accusative. A linking verb takes a predicate nominative on both sides: Iūlia est puella, never "puellam" there. Dropping the subject's twin into the accusative is a classic first-year error.
• The vocative is a whole separate set of endings to memorize. It equals the nominative except for second declension -us nouns, which end in -e.
• The order of the cases is arbitrary. The standard order groups forms that look alike, which makes the paradigms far easier to memorize.

Recap

• A case is the form a noun takes to show its job; Latin has five main cases plus the vocative.
• Nominative is subject, genitive is possessor, dative is recipient, accusative is object, ablative is by, with, from, or in.
• Linking verbs like est take a predicate nominative, not an accusative.
• The ablative splits into means (no preposition), accompaniment (cum), and place where (in).
• The vocative, for direct address, matches the nominative except in second declension -us nouns.
• Every noun also carries a number and a gender, and gender must be learned word by word.
• Name the case, and you know the role, whatever the word order.

The big picture

A declension is a group of nouns that share the same set of case endings. Latin has five declensions. We start with the first declension, whose nouns are easy to recognize: their dictionary form ends in -a, and the great majority are feminine.

You identify a noun's declension from its genitive singular, which the dictionary always lists. First declension nouns show genitive singular -ae. A typical entry looks like puella, puellae, f., meaning "girl", genitive "puellae", feminine.

The endings

Take the stem by dropping the -ae from the genitive singular. For puella the stem is puell-. Now add the endings below. The macrons mark long vowels, which matter for pronunciation and sometimes tell two forms apart.

Case	Singular	Plural	Singular meaning
Nominative	puella	puellae	the girl (subject)
Genitive	puellae	puellārum	of the girl
Dative	puellae	puellīs	to or for the girl
Accusative	puellam	puellās	the girl (object)
Ablative	puellā	puellīs	by, with, or from the girl

Learn the bare endings as a chant: -a, -ae, -ae, -am, -a in the singular, and -ae, -arum, -is, -as, -is in the plural. Say it aloud until it is automatic. The vocative, for address, is identical to the nominative throughout this declension, so puella! is also "girl!" when you call her.

To use the table, decide two things about the noun you want: its case and its number. Then read across to that cell. If you need "of the girls", you want genitive plural, which is puellārum. If you need "to the girl", you want dative singular, which is puellae. The paradigm is a small grid, and every first declension noun follows it exactly.

Here is the same grid working on a second noun, rosa, rosae, f. ("rose"), so you can see how mechanical the system is once the stem ros- is in hand.

Case	Singular	Plural
Nominative	rosa	rosae
Genitive	rosae	rosārum
Dative	rosae	rosīs
Accusative	rosam	rosās
Ablative	rosā	rosīs

Two cautions

• The ending -ae does triple duty: it is genitive singular, dative singular, and nominative plural. Context and the rest of the sentence tell you which one you have.
• The nominative singular -a is short, while the ablative singular -ā is long. Without macrons they look identical, so again you rely on context.

Two endings are pleasantly distinctive and worth noting. The genitive plural -arum is long and unmistakable, so puellārum can only mean "of the girls". The accusative singular -am is equally clear, so puellam can only be a direct object. Distinctive endings like these are anchors when you read, giving you a firm role for a word even before you have parsed the rest of the sentence.

A caution for English-trained eyes: the plural accusative -ās looks like an English plural in -s, and the temptation is to read viās as a subject, "the roads". Resist it. In the first declension a plain -ās ending is an object form; the subject plural is -ae. English instincts about -s are the single most common source of backwards translations at this stage.

Vocabulary

Most first declension nouns are feminine, but a handful naming male roles are masculine. They take the very same endings; only their gender differs, which will matter for adjective agreement. The lower rows appear in this lesson's readings.

Latin (nom., gen.)	English	Gender
puella, puellae	girl	feminine
fēmina, fēminae	woman	feminine
via, viae	road, way	feminine
silva, silvae	forest	feminine
rēgīna, rēgīnae	queen	feminine
nauta, nautae	sailor	masculine
agricola, agricolae	farmer	masculine
poēta, poētae	poet	masculine
aqua, aquae	water	feminine
īnsula, īnsulae	island	feminine
fābula, fābulae	story	feminine
vīta, vītae	life	feminine

The first declension is a good place to begin because it is very common and its endings are clean and consistent. Most words for people, places, and abstractions in early reading, such as puella, via, and patria, belong to it. Master this one grid and you already understand a large share of the nouns on a beginner's page.

Example sentences

Read each sentence, find the ending, and let it decide the role before you settle on the English.

• Rēgīna in vīllā habitat. means "The queen lives in the country house." vīllā is ablative after "in".
• Puellae rosās amant. means "The girls love roses." Puellae is nominative plural, rosās accusative plural.
• Fēmina viam nautīs mōnstrat. means "The woman shows the road to the sailors." nautīs is dative plural.
• Poēta fābulās puellīs narrat. means "The poet tells stories to the girls." Here puellīs is dative plural, and note that the identical -is ending also serves the ablative plural, so only context separates them.

Worked example: Latin into English

Translate Nautae feminam amant. Working word by word: Nautae is from nauta, and here the ending -ae is nominative plural, the subject, so "the sailors". feminam is from femina, and the -am ending is accusative singular, the object, so "the woman". amant means "they love".

Result: "The sailors love the woman." Notice how the endings, not the order, told you that the sailors do the loving. A useful note: although first declension nouns are mostly feminine, nauta, agricola, and poēta are masculine, which will matter when adjectives must agree.

How to build it: English into Latin

Now run the machine the other way. Translate "The queen gives roses to the women." Step 1, case-map the English, as Lesson 3 taught: queen = subject, nominative; roses = thing given, accusative plural; the women = recipients, dative plural. Step 2, look up each word and find its stem: rēgīn-, ros-, fēmin-. Step 3, attach the endings from the grid: nominative singular rēgīna, accusative plural rosās, dative plural fēminīs. Step 4, order the words the neutral Latin way, subject first, verb last, with the dative commonly before the accusative: Rēgīna fēminīs rosās dat. Every decision came off the paradigm; nothing was guessed.

Reading: life by the sea

Puellae in silvā ambulant. Fēminae aquam portant. Nautae ad īnsulam nāvigant. Vīta nautārum est dūra.

Translation: "The girls walk in the forest. The women carry water. The sailors sail to the island. The life of the sailors is hard."

Three comprehension notes. nautārum is the unmistakable genitive plural, "of the sailors", hanging off vīta. The phrase ad īnsulam shows the preposition ad ("toward") taking an accusative, a pairing Lesson 12 will systematize. And in the last sentence dūra ("hard") stays nominative after est, agreeing with vīta, the predicate pattern from Lesson 3.

Reading: the poet's story

A second, slightly longer passage. Every noun is first declension; parse each ending before translating.

Poēta puellīs fābulam narrat. Fābula est de rēgīnā et nautīs. Rēgīna īnsulam amat, sed nautae patriam dēsīderant. Vīta īnsulae est grata, sed via ad patriam est longa. Puellae fābulam poētae laudant.

Translation: "The poet tells the girls a story. The story is about a queen and sailors. The queen loves the island, but the sailors long for their homeland. The life of the island is pleasant, but the road to the homeland is long. The girls praise the poet's story."

Two notes. In de rēgīnā the preposition de ("about") takes the ablative, another pairing for Lesson 12's collection. And the last sentence hides the triple-duty ending: poētae is genitive singular, "the poet's", even though the same letters could be a dative or a plural; the sentence already has a subject (puellae, confirmed by the plural verb laudant) and an object (fābulam), so the genitive is the only role left. That process of elimination is exactly how Romans read.

Common misconceptions

• Every noun ending in -a is feminine. Most are, but nauta, agricola, and poēta are masculine despite their endings.
• The ending -ae can only be plural. It is also genitive singular and dative singular; only context settles the meaning.
• An -s ending means a plural subject, as in English. First declension -ās is the accusative plural, an object form; the subject plural is -ae.
• Macrons are decorations. They mark vowel length, and length distinguishes nominative puella from ablative puellā.
• The stem comes from the nominative. Take the stem from the genitive singular by dropping -ae; the nominative can mislead you.

Recap

• A declension is a family of nouns with shared endings; the first declension has genitive singular -ae.
• The singular chant is -a, -ae, -ae, -am, -a; the plural is -ae, -arum, -is, -as, -is, and the vocative matches the nominative.
• Find the stem from the genitive, then attach the endings; the grid works identically for every noun in the family.
• Most first declension nouns are feminine, but nauta, agricola, and poēta are masculine.
• The shared -ae forms, the short-versus-long -a, and the object ending -ās all rely on context, not English instincts.

The big picture

The second declension is the next big family. Its nouns are mostly masculine, with a dictionary form in -us, or neuter, with a dictionary form in -um. The tell-tale genitive singular ending is -i. A dictionary entry looks like servus, servi, m. ("slave") or bellum, belli, n. ("war").

Together the first and second declensions cover a huge share of common nouns. The first gave you feminine words in -a; the second now gives you masculine words in -us and neuter words in -um. Learn both grids and you can parse most nouns a beginner meets.

Masculine -us nouns

Take the stem by dropping -i from the genitive singular. For amicus ("friend") the stem is amic-. The endings are:

Case	Singular	Plural	Singular meaning
Nominative	amīcus	amīcī	the friend (subject)
Genitive	amīcī	amīcōrum	of the friend
Dative	amīcō	amīcīs	to or for the friend
Accusative	amīcum	amīcōs	the friend (object)
Ablative	amīcō	amīcīs	by, with, or from the friend

Chant the singular -us, -i, -o, -um, -o and the plural -i, -orum, -is, -os, -is. Notice the dative and ablative are identical in both numbers, singular -ō and plural -īs, so once again context decides.

Hold the two declensions side by side for a moment and the architecture shows through. The genitive plural is -ārum there and -ōrum here; the dative and ablative plural is -īs in both; the accusative singular ends in -m in both (-am, -um) and the accusative plural in -s with a long vowel (-ās, -ōs). Latin's declensions are variations on one melody, and hearing the shared shape halves the memory work.

Neuter -um nouns

Neuter nouns follow the same family with one crucial twist. For bellum ("war"), stem bell-:

Case	Singular	Plural	Singular meaning
Nominative	bellum	bella	the war (subject)
Genitive	bellī	bellōrum	of the war
Dative	bellō	bellīs	to or for the war
Accusative	bellum	bella	the war (object)
Ablative	bellō	bellīs	by, with, or from the war

The neuter rule

Memorize this rule now, because it holds for every neuter noun in Latin, in every declension. First, the nominative and accusative are always identical, here both bellum in the singular and both bella in the plural. Second, the nominative and accusative plural always end in -a.

This second point is a famous trap. Do not mistake bella ("wars", a neuter plural) for a first declension singular in -a like puella. The surrounding words, and the noun's known gender, will show which one you have. Compare: Dōna sunt magna, "The gifts are great", where the plural verb sunt confirms that dōna is plural despite its -a.

A special sub-type: -er nouns

A few masculine second declension nouns end in -er rather than -us, such as puer ("boy"), genitive pueri. They keep the second declension endings from the genitive on; only the nominative singular looks different. So the accusative of puer is puerum, and the nominative plural is pueri ("the boys").

Watch the stem carefully. Some -er nouns keep the e, like puer, puerī, while others drop it, like ager, agrī ("field") and magister, magistrī ("teacher"). The genitive always shows you the true stem. One more one-off worth knowing: vir, virī ("man") declines like puer, and it is the only common noun of its shape.

Vocabulary

Latin (nom., gen.)	English	Gender
servus, servī	slave	masculine
amīcus, amīcī	friend	masculine
dominus, dominī	master, lord	masculine
fīlius, fīliī	son	masculine
equus, equī	horse	masculine
vir, virī	man	masculine
puer, puerī	boy	masculine
ager, agrī	field	masculine
bellum, bellī	war	neuter
dōnum, dōnī	gift	neuter
oppidum, oppidī	town	neuter
cibus, cibī	food	masculine

Example sentences

• Servī in agrīs labōrant. means "The slaves work in the fields." agrīs is ablative plural after "in".
• Dominus amīcō equum dat. means "The master gives a horse to his friend." amīcō is dative, equum accusative.
• Bella sunt mala. means "Wars are bad." Bella is neuter nominative plural, the subject.
• Puer dōna amīcīs portat. means "The boy carries gifts to his friends." dōna is neuter accusative plural, and amīcīs is dative plural.

That last sentence packs in three second declension patterns at once: a masculine -er subject, a neuter plural object in -a, and a masculine dative plural in -īs. If you can label all three, the declension is working for you.

Worked example: Latin into English

Translate Amici bellum timent. Word by word: Amici is nominative plural, "the friends", the subject; bellum is accusative singular, "war", the object, since here the neuter nominative and accusative look the same but it is the thing feared; timent means "they fear". Result: "The friends fear war."

One habit to unlearn as you parse: the plural subject here ends in -ī, not in -s. English eyes read amīcōs as "friends do something", but that long -ōs is an object ending. In the second declension the subjects are -us and -ī; anything in -um or -ōs is being acted on.

How to build it: English into Latin

Translate "The master's sons give gifts to the boys." Case-map first: sons = subject, nominative plural; the master's = possessor, genitive singular; gifts = object, accusative plural; the boys = recipients, dative plural. Fetch stems from the genitives: fīli-, domin-, dōn-, puer-. Attach endings: fīliī, dominī, dōna (neuter plural in -a), puerīs. Order it subject, genitive with its noun, dative, object, verb last: Fīliī dominī puerīs dōna dant. Note how fīliī and dominī wear the same ending doing different jobs, nominative plural and genitive singular; their positions side by side ("the sons of-the-master") and the plural verb sort them out.

Direct address

Recall the vocative from the case lesson. It is the second declension where it actually changes shape. A masculine -us noun becomes -e in address, so amicus becomes amice ("O friend"). A noun in -ius, like filius ("son"), contracts to fili when you call to it. This is why a Roman shouted Marce! to Marcus, and why Caesar's famous dying words are reported as et tu, Brute?, with Brutus in the vocative.

Reading: work in the fields

Mārcus est puer Rōmānus. Mārcus in agrō labōrat. Servī quoque in agrīs labōrant. Dominus servīs cibum dat. Fīlius dominī equōs amat.

Translation: "Marcus is a Roman boy. Marcus works in the field. The slaves also work in the fields. The master gives food to the slaves. The master's son loves the horses."

Three notes. puer stays nominative after est, the predicate pattern again. agrō and agrīs show the e-dropping stem agr- in ablative singular and plural. And the last sentence mirrors this lesson's build-it example: Fīlius dominī is "the son of the master", with the genitive leaning on its noun, while equōs in long -ōs is the accusative plural object.

Rome in these words

This declension carries a load of Roman social history. Dominus, the master of a household, survives in English dominate, dominion, and the church's Latin Dominus for the Lord; servus gives us servant and servile, a reminder that Roman households ran on enslaved labor; ager, the field, lives on in agriculture; and vir stands behind virtue, which to a Roman first meant manly courage. Even et tu, Brute is second declension grammar: Shakespeare kept the Latin vocative because no English form could carry the same weight. When you decline these nouns you are handling the vocabulary Romans used to describe their own world, top to bottom.

Common misconceptions

• Every second declension noun ends in -us. No; neuters end in -um and a sub-group ends in -er, like puer.
• The neuter plural bella is a first declension singular. It is not. A neuter nominative and accusative plural ends in -a, so bella means "wars".
• An -s or -os ending marks a plural subject. -ōs is the accusative plural; the subject plural is -ī. English plural instincts point exactly the wrong way here.
• The stem is always the nominative minus its ending. For -er nouns like ager, agrī the e drops, so trust the genitive for the stem.
• You address a friend as amicus. In direct address the vocative shifts, giving amice.

Recap

• The second declension has masculine -us and neuter -um nouns, both with genitive singular -i.
• The masculine chant is -us, -i, -o, -um, -o; the plural is -i, -orum, -is, -os, -is.
• The neuter rule: nominative equals accusative, and their plural ends in -a, for every neuter in the language.
• The -er sub-type keeps or drops its e; the genitive reveals the stem, as in puer, puerī and ager, agrī; vir follows suit.
• In direct address a -us noun becomes -e, as in amice and et tu, Brute.

The big picture

The third declension is the largest and most varied family of Latin nouns. Its members can be masculine, feminine, or neuter, and their nominative singular comes in many shapes: rēx ("king"), cīvis ("citizen"), corpus ("body"), nōmen ("name"). What unites this crowd is one reliable marker: the genitive singular ends in -is.

Because so many common words live here, the third declension repays study. Once you trust its single clue and one habit for finding the stem, the variety stops being frightening and becomes routine. Every noun behaves like the others as soon as you reach its stem.

Always build from the genitive

The nominative is unpredictable, so you must take the stem from the genitive singular by dropping the -is. This is exactly why a dictionary always prints the genitive: it is the key to the whole noun.

• rēx, rēgis gives stem rēg-, which the nominative "rēx" hides.
• mīles, mīlitis ("soldier") gives stem mīlit-.
• nōmen, nōminis ("name") gives stem nōmin-.
• corpus, corporis ("body") gives stem corpor-.

Notice how far the stem can drift from the nominative. From rēx you would never guess rēg-, and from corpus you would never guess corpor-. The genitive removes the guesswork. English quietly inherited many of these stems: regal from rēg-, military from mīlit-, corporal from corpor-, nominal from nōmin-. If an English derivative comes to mind, you have probably found the Latin stem.

Masculine and feminine endings

Masculine and feminine third declension nouns share one set of endings. Here is rēx, rēgis, m. ("king"), stem rēg-, in all six cases and both numbers. The vocative, used in direct address, is identical to the nominative throughout this declension.

Case	Singular	Plural	Singular meaning
Nominative	rēx	rēgēs	the king (subject)
Genitive	rēgis	rēgum	of the king
Dative	rēgī	rēgibus	to or for the king
Accusative	rēgem	rēgēs	the king (object)
Ablative	rēge	rēgibus	by, with, or from the king
Vocative	rēx	rēgēs	O king (direct address)

Chant the singular endings after the nominative: -is, -ī, -em, -e; and the plural: -ēs, -um, -ibus, -ēs, -ibus. Two overlaps are worth flagging. The nominative and accusative plural are both -ēs, and the dative and ablative plural are both -ibus, so context must separate them.

One refinement belongs in even a first course. A sub-family called i-stems, mostly nouns like cīvis and urbs whose base ends in two consonants or whose nominative ends in -is, takes -ium instead of -um in the genitive plural: cīvium ("of the citizens"), urbium ("of the cities"), against rēgum and mīlitum. Recognize -ium when you meet it; producing it perfectly can wait for a second course.

Neuter third declension

Neuter nouns of the third declension obey the neuter rule you already met in the second declension. Here is nōmen, nōminis, n. ("name"), stem nōmin-.

Case	Singular	Plural	Singular meaning
Nominative	nōmen	nōmina	the name (subject)
Genitive	nōminis	nōminum	of the name
Dative	nōminī	nōminibus	to or for the name
Accusative	nōmen	nōmina	the name (object)
Ablative	nōmine	nōminibus	by, with, or from the name
Vocative	nōmen	nōmina	O name (direct address)

Two points repeat from the neuter of the second declension. The nominative and accusative are identical, here nōmen in the singular and nōmina in the plural. And the nominative and accusative plural end in -a, so corpora means "bodies" and tempora means "times". Every other ending matches the table for rēx.

Vocabulary

Learn each noun with its genitive and its gender, since neither is predictable from the nominative alone. The three neuters, corpus, nōmen, and tempus, will show the neuter pattern in action.

Latin (nom., gen.)	English	Gender
rēx, rēgis	king	masculine
mīles, mīlitis	soldier	masculine
cīvis, cīvis	citizen	masculine / feminine
dux, ducis	leader, general	masculine
urbs, urbis	city	feminine
lēx, lēgis	law	feminine
pāx, pācis	peace	feminine
vōx, vōcis	voice	feminine
māter, mātris	mother	feminine
corpus, corporis	body	neuter
nōmen, nōminis	name	neuter
tempus, temporis	time	neuter

Example sentences

Read each sentence, let the ending fix the role, then settle on the English.

• Mīlitēs rēgem laudant. means "The soldiers praise the king." rēgem is accusative singular, the object.
• Rēx mīlitibus pecūniam dat. means "The king gives money to the soldiers." mīlitibus is dative plural, the recipients.
• Nōmen rēgis clārum est. means "The king's name is famous." rēgis is genitive singular, "of the king".
• Māter fīlium amat. means "The mother loves her son." Māter is nominative, fīlium accusative.
• Cīvēs lēgēs patriae amant. means "The citizens love the laws of their homeland." lēgēs is accusative plural, patriae genitive singular.

Notice how the declensions now mix freely: pecūniam and patriae are first declension, fīlium is second, and the rest are third. Real Latin always blends the families, and your job is simply to ask of each noun: which declension, which case, which number?

Worked example: Latin into English

Translate Rēgem mīlitēs vident. Word by word: Rēgem is accusative singular ("the king", the object); mīlitēs is nominative plural ("the soldiers", the subject); vident means "they see". Even though the object stands first, the endings fix the roles.

Result: "The soldiers see the king." This is inflection at work. In English the order would decide who sees whom, but in Latin the accusative -em and the plural verb settle it no matter where the words sit.

How to build it: English into Latin

Translate "The leader gives the laws of peace to the citizens." Case-map: leader = nominative; the laws = accusative plural; of peace = genitive singular; the citizens = dative plural. Stems from the genitives: duc-, lēg-, pāc-, cīv-. Attach endings: dux (nominative as listed), lēgēs, pācis, cīvibus. Assemble, verb last, genitive next to its noun: Dux cīvibus lēgēs pācis dat. Each ending was fetched from the rēx grid; the only memory work was the stems, which the dictionary hands you.

Reading: the just king

Read the passage aloud, then check the translation and the case notes.

Rēx in urbe magnā habitat. Multī mīlitēs rēgem servant. Rēx est vir bonus et iūstus. Cīvēs rēgem amant, quod pāx in patriā est.

Translation: "The king lives in a great city. Many soldiers guard the king. The king is a good and just man. The citizens love the king, because there is peace in the homeland."

Three notes. urbe is the third declension ablative in -e after "in", sitting beside a first declension adjective form; patriā is the familiar first declension ablative. vir bonus et iūstus stays nominative after est, the predicate pattern. And quod ("because") introduces a reason clause, a small connective worth collecting for reading.

Sententiae

Three short Roman sayings, each built on third declension nouns:

• Tempus fugit. "Time flees." Tempus is a neuter noun, genitive temporis.
• Nōmen est ōmen. "A name is an omen." Both nōmen and ōmen are neuter.
• Vōx populī, vōx deī. "The voice of the people is the voice of god." Vōx is feminine, genitive vōcis; populī and deī are second declension genitives.

Sayings like these show why Romans could be so compact: each noun carries its case on its back, so a two-word sentence can be complete.

Common misconceptions

• The stem comes from the nominative. It does not. Take the stem from the genitive, so rēx yields rēg- and corpus yields corpor-.
• Third declension nouns share one gender. They come in all three genders, so you must learn the gender with each word.
• The plural -ēs is only nominative. It is also the accusative plural, and only context tells the two apart.
• The form corpora is a first declension singular in -a. It is a neuter nominative or accusative plural, "bodies".
• An ending means the same thing in every declension. It does not: -um is the accusative singular of bellum-type nouns but the genitive plural of rēx-type nouns (rēgum, "of the kings"). Always ask which declension you are in before you read an ending.
• Macrons are decoration. They mark vowel length; the long ē of rēx is a real feature of the word, not a flourish.

Recap

• The third declension is the biggest noun family; its badge is genitive singular -is.
• Build every form from the genitive stem: rēx, rēgis, stem rēg-.
• Masculine and feminine share endings: -is, -ī, -em, -e singular; -ēs, -um, -ibus, -ēs, -ibus plural; i-stems like cīvis take -ium.
• Neuters follow the neuter rule: nominative equals accusative, plural in -a, as in nōmina and corpora.
• English derivatives (regal, military, corporal) often reveal the Latin stem.
• The same letters can be different endings in different declensions; identify the declension first.

The big picture

Two smaller declensions complete the Latin noun system. Together the fourth and fifth declensions hold far fewer nouns than the first three, yet several of those nouns are among the most common words in the language, so they are well worth knowing.

You already recognize a noun's declension from its genitive singular. That single habit still works here. The fourth declension shows genitive -ūs, and the fifth shows genitive -eī. Learn those two markers and every Latin noun is finally accounted for.

The fourth declension

The fourth declension has a nominative singular in -us, just like the second, but it is set apart by its genitive singular in -ūs with a long u. Most of its nouns are masculine. Here is portus, portūs, m. ("harbor"), stem port-.

Case	Singular	Plural	Singular meaning
Nominative	portus	portūs	the harbor (subject)
Genitive	portūs	portuum	of the harbor
Dative	portuī	portibus	to or for the harbor
Accusative	portum	portūs	the harbor (object)
Ablative	portū	portibus	by, with, or from the harbor
Vocative	portus	portūs	O harbor (direct address)

The clue that separates fourth from second declension is the genitive: second is -ī, fourth is -ūs. Watch the long -ūs, which does triple duty as genitive singular, nominative plural, and accusative plural. A short handful of fourth declension nouns are feminine, most notably manus ("hand") and domus ("house"), so learn their gender with care.

Domus deserves a special word. It is the everyday word for home, and Latin gives it two fossilized forms you will meet constantly in reading: domum means "homeward, to home" and domī means "at home", both used without any preposition. Recognize them as fixed idioms for now; the grammar behind them (the accusative of motion and the old locative case) belongs to a later course.

The fifth declension

The fifth declension is the smallest of the five. Its nominative singular ends in -ēs and its genitive singular in -eī. Most of its nouns are feminine, with two important masculine exceptions: diēs ("day") and its compound merīdiēs ("midday"). Here is rēs, reī, f. ("thing, matter, affair"), stem r-.

Case	Singular	Plural	Singular meaning
Nominative	rēs	rēs	the thing (subject)
Genitive	reī	rērum	of the thing
Dative	reī	rēbus	to or for the thing
Accusative	rem	rēs	the thing (object)
Ablative	rē	rēbus	by, with, or from the thing
Vocative	rēs	rēs	O thing (direct address)

The noun diēs follows the same pattern, though its genitive is diēī with a long e, because a vowel stands before the ending. Notice how the fifth declension leans on context: the nominative and accusative plural are both rēs, and the genitive and dative singular are both reī.

These small declensions carry a few very frequent words. Learn each with its genitive and gender.

Latin (nom., gen.)	English	Declension and gender
portus, portūs	harbor, port	fourth, masculine
manus, manūs	hand; band of men	fourth, feminine
exercitus, exercitūs	army	fourth, masculine
domus, domūs	house, home	fourth, feminine
senātus, senātūs	senate	fourth, masculine
rēs, reī	thing, matter, affair	fifth, feminine
diēs, diēī	day	fifth, masculine
merīdiēs, merīdiēī	midday, noon	fifth, masculine
spēs, speī	hope	fifth, feminine
fidēs, fideī	faith, trust, loyalty	fifth, feminine

Example sentences

• Nautae in portū labōrant. means "The sailors work in the harbor." portū is ablative singular after "in".
• Rēx magnum exercitum habet. means "The king has a great army." exercitum is accusative singular, the object.
• Manūs agricolae dūrae sunt. means "The farmer's hands are rough." Manūs is nominative plural, feminine.
• Sine spē vīta dūra est. means "Without hope life is hard." spē is ablative singular after sine.
• Merīdiē amīcī in viā ambulant. means "At midday the friends walk in the road." Merīdiē is an ablative of time.

Worked example: Latin into English

Translate Senātus fidem exercitūs laudat. Word by word: Senātus could be nominative singular or several other -ūs forms; the singular verb at the end will confirm it as the subject. fidem is the fifth declension accusative singular, "faith" or "loyalty", the object. exercitūs here is genitive singular, "of the army", leaning on fidem. laudat is "praises", singular. Result: "The senate praises the loyalty of the army." Two different declensions supplied look-alike endings, and the verb plus word grouping sorted them out.

How to build it: English into Latin

Translate "The army gives hope to the citizens." Case-map: army = nominative; hope = accusative; the citizens = dative plural. Stems: exercit- (fourth), sp- (fifth), cīv- (third). Attach endings from each noun's own declension: exercitus, spem, cīvibus. Verb last: Exercitus cīvibus spem dat. Notice the discipline this demands: three nouns, three different declensions, each fetching its ending from its own grid. That is everyday Latin, and you can now do it.

Reading: a day at the harbor

Read the passage aloud, then check the translation and the notes.

Prīmā lūce nautae ad portum veniunt. Merīdiē in portū labōrant. Manibus fūnēs et vēla portant. Rēs nautārum est dūra, sed spem semper habent.

Translation: "At first light the sailors come to the harbor. At midday they work in the harbor. With their hands they carry ropes and sails. The sailors' life is hard, but they always have hope."

Three notes. ad portum is accusative because ad marks motion toward, while in portū is ablative because the sailors are now at rest there; the same harbor, two cases, two meanings. Manibus is an ablative of means, "with their hands", no preposition needed. And Rēs nautārum, literally "the affair of the sailors", is idiomatic Latin for their situation or life, with the first declension genitive plural nautārum hanging on a fifth declension noun.

The whole system at a glance

You can now recognize any Latin noun by its genitive singular. Memorize this master key, which sums up all five declensions in a single grid.

Declension	Genitive singular	Typical gender	Example
First	-ae	feminine	puella, puellae
Second	-ī	masculine / neuter	amīcus, amīcī; bellum, bellī
Third	-is	all three	rēx, rēgis
Fourth	-ūs	mostly masculine	portus, portūs
Fifth	-eī	mostly feminine	rēs, reī

This single table is the backbone of Latin noun morphology. When you meet a new noun, check its genitive, slot it into one of these five patterns, and you know how it will behave in every case.

Rome in these words

These two small declensions carry a surprising amount of Roman culture into English. The Roman state called itself the rēs pūblica, "the public thing", which is where the word republic comes from; Augustus titled his memoir Rēs Gestae, "things done". From diēs come diary, per diem, and the motto carpe diem, "seize the day", where diem is the accusative you just learned. From manus come manual and manuscript, "written by hand"; from senātus, senate itself, literally a council of elders. Meeting a paradigm and finding half of English civics vocabulary inside it is a very Latin experience.

Common misconceptions

• A noun in -us must be second declension. Check the genitive. Fourth declension nouns like portus, portūs also end in -us but show genitive -ūs.
• All fourth declension nouns are masculine. Several common ones are feminine, above all manus and domus.
• All fifth declension nouns are feminine. The words diēs and merīdiēs are masculine.
• The fifth declension is large. It is the smallest of the five, holding only a few nouns, yet they appear constantly.
• -ibus belongs only to the third declension. The fourth declension shares it (portibus), one more reason to identify the declension from the genitive rather than from a single ending.
• The genitive of rēs and diēs look the same. They differ: reī has a short e, while diēī has a long e, because a vowel precedes the ending.

Recap

• The fourth declension has nominative -us but genitive -ūs; most nouns are masculine, though manus and domus are feminine.
• The fifth declension has nominative -ēs and genitive -eī; most nouns are feminine, but diēs and merīdiēs are masculine.
• The long -ūs of the fourth declension serves genitive singular, nominative plural, and accusative plural at once.
• The fifth declension noun rēs shows rem, reī, rē, and plural rēs, rērum, rēbus.
• domum means homeward and domī at home, fixed idioms of domus.
• The master key is the genitive singular: -ae, -ī, -is, -ūs, -eī for the five declensions, and rēs pūblica, carpe diem, and manuscript all live inside these paradigms.

The big picture

Just as nouns fall into declensions, verbs fall into conjugations, groups that share the same set of endings. Latin has four conjugations. We focus on the first two, which are the most regular, and once you know them the others come easily.

You identify a verb's conjugation from its present infinitive, the "to..." form. A first conjugation verb ends in -āre, as in amāre ("to love"). A second conjugation verb ends in -ēre with a long e, as in monēre ("to warn"). To get the present stem, drop the -re, giving amā- and monē-.

How a dictionary lists a verb

A Latin dictionary lists a verb by its principal parts, a small set of key forms. For the first conjugation they run amō, amāre, amāvī, amātum: "I love", "to love", "I loved", and the supine "loved". The first two are all you need for the present tense; the last two build the perfect tenses in a later course.

The great advantage of the first conjugation is regularity. Nearly every -āre verb follows amō, amāre, amāvī, amātum exactly. The second conjugation is a little more varied in the last two parts, as in moneō, monēre, monuī, monitum, but its present tense is just as predictable.

Personal endings

Latin verbs do not need a separate word for "I", "you", or "he". The ending itself tells you the person (1st is I or we, 2nd is you, 3rd is he, she, it, or they) and the number. The core present-tense endings are:

Person	Ending	Meaning
1st singular	-ō	I
2nd singular	-s	you (one person)
3rd singular	-t	he / she / it
1st plural	-mus	we
2nd plural	-tis	you (more than one)
3rd plural	-nt	they

These six endings are the most valuable half-dozen letters in Latin: they return in nearly every tense you will ever learn. A warning for English eyes: on a Latin verb, -s does not mean plural. It means "you". amās is "you love", one person; "they love" is amant.

First conjugation: amāre ("to love")

Person	Latin	English
1st sg	amō	I love (the stem vowel a merges into the -ō)
2nd sg	amās	you love
3rd sg	amat	he / she / it loves
1st pl	amāmus	we love
2nd pl	amātis	you (plural) love
3rd pl	amant	they love

Generations of schoolchildren have chanted "amō, amās, amat, amāmus, amātis, amant" for over a thousand years; join them, out loud, until the rhythm is automatic. Notice too that the stem vowel shortens before -t and -nt (amat, amant), a small, regular sound rule.

Second conjugation: monēre ("to warn")

Person	Latin	English
1st sg	moneō	I warn (here the e is kept before -ō)
2nd sg	monēs	you warn
3rd sg	monet	he / she / it warns
1st pl	monēmus	we warn
2nd pl	monētis	you (plural) warn
3rd pl	monent	they warn

Set the two side by side and one difference stands out. In the first conjugation the "I" form contracts, giving amō rather than "amaō", while the second keeps its vowel, giving moneō. Everywhere else the endings -s, -t, -mus, -tis, -nt are shared. Learn amō and moneō as your two models and you can conjugate hundreds of verbs.

Saying no, and asking

Two small words multiply what you can say. To negate any verb, place nōn directly before it: Puella nōn cantat, "The girl does not sing." Latin needs no helper like English "does"; nōn alone does the work. To ask a yes-or-no question, Latin most often hangs the little tag -ne on the first word: Amatne puella poētam?, "Does the girl love the poet?" Recognize -ne when you read; there is no English word to translate it, only the question mark it creates.

Vocabulary

Each verb is listed by all four principal parts. For the present tense you need only the first two.

Principal parts	English	Conjugation
amō, amāre, amāvī, amātum	to love	first
laudō, laudāre, laudāvī, laudātum	to praise	first
portō, portāre, portāvī, portātum	to carry	first
vocō, vocāre, vocāvī, vocātum	to call	first
moneō, monēre, monuī, monitum	to warn, advise	second
videō, vidēre, vīdī, vīsum	to see	second
habeō, habēre, habuī, habitum	to have, hold	second
doceō, docēre, docuī, doctum	to teach	second

Translating the present

The Latin present covers three English shades at once. Amat can mean "he loves", "he is loving", or "he does love", depending on context. Choose the smoothest English for the sentence. Because the ending already carries the subject, a one-word Latin verb is often a full sentence: amāmus alone means "we love".

How to build it: verb first, then the rest

Translate "We are calling the sailors." Start with the verb, since it carries the most information. To call is vocāre, first conjugation; stem vocā-; "we" takes -mus: vocāmus. That single word is already a grammatical sentence. Now the object: the sailors, accusative plural of nauta, is nautās. Assemble with the verb last: Nautās vocāmus. Two words for eight of English. Now negate it, Nautās nōn vocāmus ("We are not calling the sailors"), and turn it into a question, Vocāmusne nautās? ("Are we calling the sailors?"). One stem, one ending, and the whole toolkit of this lesson in action.

Worked example: reading a verb precisely

Parse Magister puellās nōn videt. The verb videt ends in -t: third singular, "he/she sees", second conjugation. nōn negates it. Magister is nominative singular, the see-er; puellās is accusative plural, the ones not seen. Result: "The teacher does not see the girls." Had the sentence read Magistrum puellae nōn vident, the endings would flip every role: "The girls do not see the teacher." Verb ending first, noun endings second, order last: that is the reading discipline.

Example sentences

• Puella rosam portat. means "The girl carries a rose." portat is 3rd singular present.
• Magister puerōs docet. means "The teacher teaches the boys." docet is a second conjugation verb.
• Nautae perīcula timent. means "The sailors fear dangers." timent is 3rd plural.
• Amīcum vocō. means "I call my friend." The ending -ō supplies "I", so no separate pronoun is needed.
• Rēgīnam laudāmus. means "We praise the queen." The ending -mus supplies "we".
• Habetne rēx exercitum? means "Does the king have an army?" The tag -ne makes it a question.

Reading: girls in the garden

Read the passage aloud, then check the translation and the verb notes.

Cornēlia in hortō ambulat. Rosās videt et amat. Iūlia quoque in hortō est; fābulam nārrat. Puellae rīdent et cantant. Magister puellās vocat, sed puellae magistrum nōn audiunt.

Translation: "Cornelia walks in the garden. She sees the roses and loves them. Julia too is in the garden; she tells a story. The girls laugh and sing. The teacher calls the girls, but the girls do not hear the teacher."

Three notes. Every verb ending is doing subject work: ambulat, videt, amat, and nārrat are singular (Cornelia, then Julia), while rīdent, cantant, and audiunt are plural (the girls). Rosās videt et amat shows Latin dropping the object pronoun the second time, "sees the roses and loves (them)". And in the last sentence the two nouns swap roles across the comma, magister nominative then magistrum accusative, so the endings, not the order, tell you who ignores whom.

Common misconceptions

• A Latin verb needs a separate pronoun for its subject. It does not. The ending carries the person, so amāmus means "we love" by itself.
• -s on a verb marks a plural, as on English nouns. On a Latin verb -s means "you (singular)"; the plural people are -mus, -tis, -nt.
• The two conjugations differ in every form. They differ only in the stem vowel and the contracted "I" form; the endings -s, -t, -mus, -tis, -nt are identical.
• The present has a single English translation. One Latin present covers "loves", "is loving", and "does love".
• The stem is the whole infinitive. Drop the -re to reach the present stem, giving amā- and monē-.
• An infinitive like amāre is a command. It means "to love"; commands use a separate form you will meet later.

Recap

• Verbs fall into conjugations; the first ends its infinitive in -āre, the second in -ēre.
• Drop the -re from the infinitive to find the present stem, as in amā- and monē-.
• The personal endings are -ō, -s, -t, -mus, -tis, -nt and mark person and number; they return in every tense.
• nōn before the verb negates it, and the tag -ne asks a yes-or-no question.
• One Latin present form covers three English shades: loves, is loving, does love.
• Dictionaries list verbs by principal parts; the first two build the whole present tense.

The big picture

You now have the present. Two more tenses let you speak about the past and the future. Both are built on the same present stem you already know, amā- and monē-, with a special tense marker inserted between the stem and the personal ending.

This is the payoff of a regular system. You do not learn a whole new verb for the past; you slot a marker into the machine you already own. One syllable moves an action from now to then, or from now to later.

The imperfect tense

The imperfect describes a continuous or repeated action in the past: "was loving", "used to love", "kept warning". Its marker is -bā-, placed between the stem and the ending. The second conjugation inserts a connecting e, giving the shape -ēbā-. Note the 1st singular ends in -m, not -ō.

Person	amāre (1st)	monēre (2nd)	English
1st sg	amābam	monēbam	I was loving / warning
2nd sg	amābās	monēbās	you were loving / warning
3rd sg	amābat	monēbat	he/she/it was loving / warning
1st pl	amābāmus	monēbāmus	we were loving / warning
2nd pl	amābātis	monēbātis	you were loving / warning
3rd pl	amābant	monēbant	they were loving / warning

Everywhere you see -bā-, think "was" or "were" doing something in the past. The imperfect is the tense of description and habit, the background against which single events happen. The name itself says so: imperfectum means "not finished". English speakers should note the contrast with their own grammar: English has one simple past, "the farmer worked", for both a single event and a habit, while Latin insists on marking the ongoing, repeated kind with -bā-. (The tense for single completed events, the perfect, belongs to your next course.)

The future tense

For the first and second conjugations, the future ("will love", "will warn") uses the marker -bi-, which surfaces as -bō in the first person and -bu- in the third plural. The pattern is stem plus -bi- plus ending.

Person	amāre (1st)	monēre (2nd)	English
1st sg	amābō	monēbō	I will love / warn
2nd sg	amābis	monēbis	you will love / warn
3rd sg	amābit	monēbit	he/she/it will love / warn
1st pl	amābimus	monēbimus	we will love / warn
2nd pl	amābitis	monēbitis	you will love / warn
3rd pl	amābunt	monēbunt	they will love / warn

Be aware that this -bi- future belongs only to the first and second conjugations. The third and fourth build their future differently, which you will meet in a later course.

Words that set the clock

Time adverbs signal which tense to expect, so learn a small kit of them alongside the endings.

Latin	English	Typical tense
nunc	now	present
hodiē	today	present
ōlim	once, long ago	imperfect
cotīdiē	every day	present or imperfect
semper	always	any tense
crās	tomorrow	future

Vocabulary

Practice the two new tenses on these regular verbs, each shown with its four principal parts.

Principal parts	English	Conjugation
ambulō, ambulāre, ambulāvī, ambulātum	to walk	first
labōrō, labōrāre, labōrāvī, labōrātum	to work	first
nārrō, nārrāre, nārrāvī, nārrātum	to tell, relate	first
pugnō, pugnāre, pugnāvī, pugnātum	to fight	first
videō, vidēre, vīdī, vīsum	to see	second
teneō, tenēre, tenuī, tentum	to hold, keep	second
moveō, movēre, mōvī, mōtum	to move	second
terreō, terrēre, terruī, territum	to frighten	second

Telling the tenses apart

The three tenses are easy to distinguish once you watch the space between stem and ending:

• No marker (stem plus ending) is the present: amat means "he loves".
• Marker -bā- is the imperfect: amābat means "he was loving".
• Marker -bi- (or -bō, -bu-) is the future: amābit means "he will love".

These three little forms, amat, amābat, and amābit, differ by a single syllable but move you across present, past, and future. Master that contrast and you can place any action in time.

How to build it: setting a sentence in time

Translate "The girls will tell a story." Subject: the girls, nominative plural, puellae. Object: a story, accusative singular, fābulam. Verb: to tell is nārrāre, first conjugation, stem nārrā-; future needs -bi- plus the "they" ending -nt, which fuses to -bunt: nārrābunt. Assemble, verb last: Puellae fābulam nārrābunt. Now move the same sentence into the past habit: swap the marker, nārrābant, "the girls used to tell a story". One syllable did all the time-travel; nothing else in the sentence changed.

Example sentences

• Agricola in agrō labōrābat. means "The farmer was working in the field." labōrābat is imperfect.
• Puellae in silvā cantābant. means "The girls were singing in the forest." cantābant is imperfect, 3rd plural.
• Mīlitēs hostēs timēbant. means "The soldiers were fearing the enemy." timēbant is a second conjugation imperfect.
• Crās amīcōs vocābimus. means "Tomorrow we will call our friends." vocābimus is future, 1st plural.
• Rēx bellum parābit. means "The king will prepare for war." parābit is future, 3rd singular.
• Tenēbisne equum? means "Will you hold the horse?" Future 2nd singular with the question tag -ne.

Reading: farmers of old Italy

Read the passage aloud, then check the translation and the tense notes.

Ōlim in Italiā multī agricolae habitābant. Cotīdiē in agrīs labōrābant et frūmentum portābant. Vīta erat dūra, sed Rōmānī patriam amābant. Crās quoque agricolae labōrābunt.

Translation: "Once many farmers lived in Italy. Every day they worked in the fields and carried grain. Life was hard, but the Romans loved their homeland. Tomorrow too the farmers will work."

Three notes. The opening adverbs do exactly what the table promised: ōlim and cotīdiē announce the imperfects habitābant, labōrābant, and portābant, while crās flags the future labōrābunt. The little word erat ("was") is the imperfect of the irregular verb sum, whose full story is the next lesson; meet it here as a preview. And notice the imperfects painting background and habit, "used to live, worked every day", exactly the continuous past this tense exists for.

Worked example: one letter, two worlds

Parse Puerī magistrum nōn movēbunt. Start at the verb: movēbunt breaks into stem movē-, marker -bu-, ending -nt: future, "they will move". nōn negates it. Puerī is nominative plural, the subject; magistrum accusative singular, the object. Result: "The boys will not move the teacher." Now change one letter, movēbant: the marker becomes -ba- and the whole scene slides into the past, "the boys were not moving the teacher". Train your eye to catch that vowel before anything else; in fast reading, the a-versus-i inside the verb is the difference between memory and prediction.

Reading: tomorrow's plans

A second, shorter passage, this time looking forward. Read it aloud, then check the translation.

Crās nautās vidēbimus. Nautae fābulās nārrābunt et puellae cantābunt. Poēta rēgīnam laudābit. Laetī erimus.

Translation: "Tomorrow we will see the sailors. The sailors will tell stories and the girls will sing. The poet will praise the queen. We will be happy." Every verb wears the future marker: vidēbimus, nārrābunt, cantābunt, laudābit, and finally erimus, another form of sum for the next lesson to explain in full.

Common misconceptions

• The imperfect is a simple past ("loved"). It is continuous or repeated: "was loving", "used to love", "kept loving".
• The 1st singular imperfect ends in -ō. It ends in -m, as in amābam; the form amābō with -ō is the future.
• The -bi- future works for every conjugation. It is only for the first and second; the third and fourth form the future another way.
• The forms amābat and amābit mean the same. The vowel differs: -ba- is past, -bi- is future. The same single-letter trap separates amābāmus ("we were loving") from amābimus ("we will love"), and amābant from amābunt.
• The tense marker attaches to the personal ending. It sits between stem and ending: stem plus -bā- or -bi- plus the ending.

Recap

• The imperfect and future are built on the present stem plus a tense marker before the ending.
• The imperfect marker is -bā- (second conjugation -ēbā-) for continuous or repeated past action.
• The future of the first two conjugations uses -bi-, surfacing as -bō and -bu-.
• The 1st singular imperfect ends in -m (amābam); the 1st singular future ends in -ō (amābō).
• Time adverbs steer the tense: ōlim and cotīdiē toward the imperfect, crās toward the future.
• Present, imperfect, and future differ by one syllable: amat, amābat, amābit.

The big picture

The single most common verb in Latin is sum ("to be"). Like "to be" in English (I am, you are, he is), it is irregular. You cannot predict its forms from a tidy stem, so you memorize them directly. The infinitive is esse ("to be"), and its principal parts are sum, esse, fuī, futūrus.

Do not let the word "irregular" worry you. There are only eighteen forms across the three tenses you need now, and they appear so often that they lodge in memory quickly. English "essence" and "future" both descend from this very verb, so its shapes are already half familiar.

The three tenses of sum

Person	Present (am/is/are)	Imperfect (was/were)	Future (will be)
1st sg	sum (I am)	eram (I was)	erō (I will be)
2nd sg	es (you are)	erās (you were)	eris (you will be)
3rd sg	est (he/she/it is)	erat (he was)	erit (he will be)
1st pl	sumus (we are)	erāmus (we were)	erimus (we will be)
2nd pl	estis (you are)	erātis (you were)	eritis (you will be)
3rd pl	sunt (they are)	erant (they were)	erunt (they will be)

Notice that the familiar personal endings still peek through: the -s of "you", the -t of "he", the -mus of "we", the -nt of "they". Even an irregular verb keeps those signals, which is a great help in recognizing its forms.

Past and future by the vowel

The imperfect and future both begin with er-, but the vowel that follows tells them apart. The imperfect uses era- (eram, erās, erat), while the future uses eri- (eris, erit, erimus), with the two ends of the future being erō and erunt.

So a single letter decides the time frame. Erat means "he was" and erit means "he will be". Say the two triplets aloud, eram, erās, erat and erō, eris, erit, until the a of the past and the i of the future are automatic. This is the same a-versus-i signal you drilled with amābat and amābit, resurfacing inside an irregular verb.

Vocabulary

Because sum links a subject to a describing word, it pairs constantly with predicate nouns and adjectives. Here are common ones to build sentences with. Notice how the dictionary lists an adjective in three forms, masculine, feminine, and neuter; the next lesson explains why.

Latin	English	Type
vir, virī	man	noun, masculine
deus, deī	god	noun, masculine
rēgīna, rēgīnae	queen	noun, feminine
laetus, laeta, laetum	happy, glad	adjective
clārus, clāra, clārum	famous, clear	adjective
validus, valida, validum	strong	adjective
līber, lībera, līberum	free	adjective

sum as a linking verb

Unlike "love" or "warn", sum does not take a direct object. Instead it links a subject to a word that renames or describes it. That word goes in the nominative, not the accusative, because it refers back to the subject. When the word is a noun, we call it a predicate nominative.

• Poēta amīcus est. means "The poet is a friend." Both poēta and amīcus are nominative, and est links them.
• Puellae rēgīnae sunt. means "The girls are queens." A plural subject takes plural sunt and a plural predicate nominative.

Keep this rule in mind: after any form of sum, use the nominative, never the accusative. A predicate adjective behaves the same way and must agree with the subject in gender, number, and case, as in Rōma clāra est ("Rome is famous").

There is, there are

Sum has a second everyday job: stating that something exists. When est or sunt opens the clause or stands with no describing word, translate with English "there is" or "there are": In viā sunt puellae, "There are girls in the road"; In urbe est templum, "There is a temple in the city". Nothing changes grammatically, the subject is still nominative; only the smoothest English translation shifts.

How to build it: agreement across the verb

Translate "The queen will be happy." Subject: rēgīna, nominative singular feminine. Verb: future third singular of sum, erit. The predicate adjective must copy the subject's gender, number, and case: feminine, singular, nominative, so laeta, not laetus. Assemble: Rēgīna laeta erit. Now pluralize every moving part: "The queens will be happy" becomes Rēgīnae laetae erunt, three words each stepping to the plural together. Agreement across sum is a chain, and every link must move at once.

Example sentences

• Poēta amīcus meus est. means "The poet is my friend." est is present.
• Rōma clāra erat. means "Rome was famous." erat is imperfect, and clāra agrees with feminine Rōma.
• Fēminae laetae sunt. means "The women are happy." laetae is a predicate adjective, nominative plural.
• Nautae validī erunt. means "The sailors will be strong." erunt is future.
• Vir bonus erō. means "I will be a good man." Even in the future, the predicate vir bonus stays nominative.
• In silvā sunt equī. means "There are horses in the forest." Existence, stated with sunt.

Worked example

Translate Nautae erāmus. Here nautae is nominative plural ("sailors") and erāmus is the imperfect "we were". Since sum links a subject to a predicate nominative, the sentence means "We were sailors." The verb ending already supplies "we", so no separate pronoun is needed.

Looking ahead: the family of sum

Sum is the parent of a whole family of compound verbs you will meet soon: possum ("I am able, I can"), absum ("I am away"), adsum ("I am present"). Each simply glues a prefix onto the forms you have just learned, so aderat means "he was present" and aberunt "they will be away". Learn sum well and its children come almost free. The Romans also liked the verb in their mottoes: esse quam vidērī, "to be, rather than to seem", is still the motto of schools and one American state, and it runs on the bare infinitive esse.

Worked example: reading the tenses of sum

Parse Ōlim servī erāmus; nunc līberī sumus; semper amīcī erimus. Take it clause by clause, verb first. erāmus: era- past, -mus we, "we were"; with predicate servī, "once we were slaves". sumus: present, "we are"; with līberī, "now we are free (men)". erimus: eri- future, "we will be"; with amīcī, "we will always be friends". Three clauses, one verb, three times, every predicate nominative agreeing masculine plural with the unseen "we". The sentence is practically a grammar lesson in the shape of a life story, and freedmen in Rome could have said it word for word.

Reading: Rome across time

Read the passage aloud, then check the translation and the tense notes.

Ōlim Rōma parva erat. Nunc Rōma magna et clāra est. In urbe multī cīvēs sunt. Cīvēs Rōmānī laetī sunt, quod līberī sunt. Semper amīcī Rōmae erimus.

Translation: "Once Rome was small. Now Rome is great and famous. In the city there are many citizens. The Roman citizens are happy, because they are free. We will always be friends of Rome."

Three notes. Watch the tenses shift on the adverbs, exactly as in the last lesson: ōlim with imperfect erat, nunc with present est, and the closing promise in future erimus. The third sentence is the existence pattern, "there are many citizens". And amīcī Rōmae pairs a predicate nominative with a genitive, "friends of Rome", two cases cooperating in three words.

Common misconceptions

• sum takes a direct object in the accusative. It does not. It links, so the predicate word stays in the nominative. "Rēgīnam est" is never Latin.
• The forms of sum follow a regular stem. They are irregular and must be memorized, though the endings -s, -t, -mus, -nt still show through.
• eram and erō belong to different verbs. They are the imperfect and future of the same verb; era- is past, eri- (with erō) is future.
• est must mean "eats". It means "is". The look-alike ēst with a long e means "he eats", from a different verb, so the macron matters.
• A predicate adjective need not agree. It agrees with the subject in gender, number, and case, as in Rōma clāra est.
• est and sunt always translate as "is" and "are". Standing first or alone they often mean "there is" and "there are": Sunt multī cīvēs, "There are many citizens".

Recap

• sum ("to be"), infinitive esse, is the most common and most irregular Latin verb.
• Present is sum, es, est, sumus, estis, sunt; imperfect runs eram to erant; future runs erō to erunt.
• The imperfect stem is era-, the future eri-, with the endpoints erō and erunt.
• sum links a subject to a predicate nominative, so after it you use the nominative, never the accusative.
• A predicate adjective agrees with the subject in gender, number, and case, and est/sunt can state existence, "there is / there are".
• Compounds like possum, adsum, and absum ride directly on the forms of sum.

The big picture

An adjective describes a noun: "good", "big", "Roman". In Latin an adjective is not free to take any form it likes. It must agree with its noun, and the rule is short and absolute:

An adjective agrees with its noun in gender, number, and case.

That is three things at once. If the noun is feminine, singular, and accusative, then the adjective must be feminine, singular, and accusative too. Agreement is how Latin shows which adjective belongs to which noun, even when the two stand far apart in the sentence. English marks none of this ("good girl, good boys, of the good wars", always "good"), so agreement is a genuinely new habit, and the payoff is the freedom of Latin word order.

First-second declension adjectives

The most common adjectives use first declension endings for the feminine and second declension endings for the masculine and neuter. Their dictionary form lists all three genders, for example bonus, bona, bonum ("good").

• bonus is masculine and uses second declension -us endings, like amīcus.
• bona is feminine and uses first declension -a endings, like puella.
• bonum is neuter and uses second declension neuter endings, like bellum.

So the adjective simply borrows endings you already know. Nothing here is new except the idea of choosing the right column to match the noun's gender. A few adjectives of this family have a masculine in -er, echoing puer and ager: pulcher, pulchra, pulchrum ("beautiful") drops its e outside the masculine nominative, while līber, lībera, līberum ("free") keeps it. As with the nouns, the feminine form shows you the true stem.

The full adjective paradigm

Because an adjective can describe a noun in any case, it declines fully in all three genders. Here is bonus, bona, bonum in the singular.

Case	Masculine	Feminine	Neuter
Nominative	bonus	bona	bonum
Genitive	bonī	bonae	bonī
Dative	bonō	bonae	bonō
Accusative	bonum	bonam	bonum
Ablative	bonō	bonā	bonō
Vocative	bone	bona	bonum

And here is the plural, which follows the same three declensions.

Case	Masculine	Feminine	Neuter
Nominative	bonī	bonae	bona
Genitive	bonōrum	bonārum	bonōrum
Dative	bonīs	bonīs	bonīs
Accusative	bonōs	bonās	bona
Ablative	bonīs	bonīs	bonīs
Vocative	bonī	bonae	bona

Read the masculine column and you see amīcus; read the feminine and you see puella; read the neuter and you see bellum. The neuter still obeys its rule: nominative equals accusative, and their plural is bona.

Making it agree

To make the adjective agree, put it in the same gender column and the same case row as its noun.

Noun (with gender)	Add "good"	Meaning
puella (fem. nom. sg.)	puella bona	a good girl
amīcus (masc. nom. sg.)	amīcus bonus	a good friend
bellum (neut. nom. sg.)	bellum bonum	a good war
puellam (fem. acc. sg.)	puellam bonam	a good girl (as object)
amīcī (masc. nom. pl.)	amīcī bonī	good friends

Agreement is not the same as rhyming

A subtle but vital point: agreement means matching gender, number, and case, not necessarily having the same letters. Recall the masculine noun nauta ("sailor"), which uses first declension endings but is masculine. To say "a good sailor", the adjective must be masculine, so you use bonus, giving nauta bonus, even though the two words do not look alike. The adjective agrees in gender, not in surface spelling. The same logic pairs a third declension noun with this family of adjectives: "a good king" is rēx bonus, and "of the good mother" is mātris bonae, each adjective fetching its ending from its own paradigm while copying the noun's gender, number, and case.

Vocabulary

These adjectives all follow the bonus, bona, bonum pattern, so once you can decline one you can decline them all.

Latin (m., f., n.)	English
bonus, bona, bonum	good
magnus, magna, magnum	big, great
parvus, parva, parvum	small
malus, mala, malum	bad, evil
multus, multa, multum	much, many
longus, longa, longum	long
pulcher, pulchra, pulchrum	beautiful
Rōmānus, Rōmāna, Rōmānum	Roman

English has quietly borrowed this whole table: magnitude and magna cum laude from magnus, malice from malus, multitude from multus, longitude from longus, and the word bonus itself, which is simply the Latin masculine "good" turned into a paycheck.

Example sentences

• Puella bona in vīllā magnā habitat. means "The good girl lives in a big house." bona is nominative, magnā ablative.
• Agricola bonus agrōs magnōs habet. means "The good farmer has big fields." magnōs is accusative plural.
• Bella longa mala sunt. means "Long wars are bad." All three words are neuter nominative plural.
• Nauta bonus fābulās multās nārrat. means "The good sailor tells many stories." bonus is masculine, multās feminine accusative plural.

Adjectives standing alone

Latin can drop the noun entirely and let the adjective's ending imply it, a use called the substantive. Bonī by itself means "the good men" or "good people"; bona (neuter plural) means "good things"; multa means "many things". So the proverb-like Bonī bona amant means "Good people love good things", two adjectives, no nouns, and the endings carry the whole sentence. English needs helper nouns ("people", "things"); Latin's endings make them unnecessary.

How to build it: the agreement chain

Translate "The Roman queen sees the small boys." Subject: the queen, nominative singular feminine, rēgīna; Roman must copy all three tags, feminine nominative singular: Rōmāna. Object: the boys, accusative plural masculine, puerōs; small copies those tags: parvōs. Verb: videt, third singular, last. Assemble: Rēgīna Rōmāna puerōs parvōs videt. Two noun-adjective pairs, each wearing matching uniforms; even shuffled for emphasis (Puerōs parvōs rēgīna Rōmāna videt) the uniforms keep every word with its partner.

Reading: Cornelia at home

Read the passage aloud, then check the translation and the agreement notes.

Cornēlia est puella Rōmāna. In vīllā magnā habitat. Vīlla pulchra est et hortum magnum habet. Cornēlia amīcōs bonōs habet. Puellae bonae in hortō laetae sunt.

Translation: "Cornelia is a Roman girl. She lives in a big house. The house is beautiful and has a big garden. Cornelia has good friends. The good girls are happy in the garden."

Three notes. Trace the agreements: puella Rōmāna (fem. nom.), vīllā magnā (fem. abl.), hortum magnum (masc. acc.), amīcōs bonōs (masc. acc. pl.). Vīlla pulchra est shows a predicate adjective agreeing across est, the pattern from the sum lesson. And in the last sentence bonae and laetae both agree with puellae even though one touches the noun and the other stands beyond the prepositional phrase; agreement, not adjacency, ties them.

Position and word order

Latin adjectives often follow their noun, as in puella bona, though adjectives of size or quantity frequently come first, as in magna vīlla. Because agreement, not position, ties the pair together, the exact order is flexible and can shift for emphasis. When you translate, gather each noun with the adjective that matches it in gender, number, and case, wherever the two happen to fall in the line.

Worked example

Translate Agricolae bonī fīliās parvās amant. The verb amant is "they love". The phrase agricolae bonī is masculine nominative plural, "the good farmers", the subject. The phrase fīliās parvās is feminine accusative plural, "small daughters", the object.

Result: "The good farmers love their small daughters." Notice that bonī agrees with a first declension noun that happens to be masculine, while parvās agrees with a feminine one. Neither adjective copies its noun's letters; each copies its gender, number, and case.

Common misconceptions

• An adjective must share the same ending as its noun. It shares gender, number, and case, which can produce different endings, as in nauta bonus.
• "Nauta bona" is correct because both end in -a. It is wrong: nauta is masculine, so only nauta bonus agrees. Rhyme is not agreement.
• An adjective must sit right beside its noun. Position is flexible; agreement links them even when other words come between.
• An adjective agrees with the nearest noun. It agrees with its own noun. In fīlia agricolae bona, bona is feminine and can only describe fīlia, "the farmer's good daughter", not the farmer.
• An adjective needs a noun to stand on. Substantives stand alone: bonī, "good men"; bona, "good things".
• The neuter plural adjective in -a is a feminine singular. Bella longa mala sunt is all neuter plural; the verb sunt confirms it.

Recap

• Adjectives agree with their nouns in gender, number, and case, the three tags at once.
• First-second declension adjectives run bonus (like amīcus), bona (like puella), bonum (like bellum); pulcher-types drop their e.
• Agreement means matching categories, not matching letters: nauta bonus, rēx bonus.
• Substantive adjectives stand alone: bonī are good men, bona are good things.
• Position is free; agreement, not adjacency, pairs adjective with noun.
• English keeps this table in its pocket: bonus, magnitude, multitude, longitude.

The big picture

A preposition is a small word placed before a noun to show a relationship: "in", "into", "with", "from", "toward". English does the same, but Latin adds a rule. Every preposition governs a specific case for the noun that follows it. That noun is the object of the preposition, and it is never nominative, since the nominative is reserved for the subject.

In Latin, prepositions take either the accusative or the ablative. You memorize which case each one governs, and after a little practice the pairing becomes second nature. English actually keeps a shadow of this rule in its pronouns: you say "with him", never "with he", putting the pronoun in its object form after the preposition. Latin simply applies that logic to every noun, and lets the choice of case add meaning.

Prepositions with the accusative

These generally express motion toward or through something, or a physical relation in space.

Preposition	Meaning	Example	Translation
ad	to, toward	ad vīllam	to the farmhouse
in (+ acc.)	into	in vīllam	into the farmhouse
per	through	per silvam	through the forest
trāns	across	trāns viam	across the road
ante	before, in front of	ante templum	in front of the temple
post	after, behind	post bellum	after the war
prope	near	prope oppidum	near the town
contrā	against	contrā hostēs	against the enemy

Prepositions with the ablative

These generally express position, separation, or accompaniment.

Preposition	Meaning	Example	Translation
in (+ abl.)	in, on	in vīllā	in the farmhouse
cum	with	cum amīcō	with a friend
ex / ē	out of, from	ex vīllā	out of the farmhouse
ab / ā	from, away from	ab oppidō	from the town
sine	without	sine aquā	without water
dē	down from, about	dē mūrō	down from the wall
prō	for, on behalf of	prō patriā	for the homeland
sub (+ abl.)	under	sub terrā	under the ground

The two faces of "in"

The single most important preposition to watch is in, because it takes different cases with different meanings.

• in plus the accusative means motion into: in vīllam ambulat means "she walks into the farmhouse".
• in plus the ablative means rest in or on: in vīllā manet means "she stays in the farmhouse".

The case ending on the noun tells you which meaning is intended. This is a real payoff of the case system: one little word covers both "into" and "in", and the noun's ending settles the difference. The preposition sub behaves the same way, taking the accusative for motion and the ablative for rest. Set the four possibilities side by side once and the system locks in:

Phrase	Case	Meaning
in aquam	accusative	into the water (motion)
in aquā	ablative	in the water (rest)
sub mūrum	accusative	to a spot under the wall (motion)
sub mūrō	ablative	under the wall (rest)

Vocabulary

These nouns of place and thing are the ones prepositions most often govern. Learn each with its genitive and gender, since the object must take the accusative or ablative form.

Latin (nom., gen.)	English	Gender
oppidum, oppidī	town	neuter
vīlla, vīllae	farmhouse, country house	feminine
urbs, urbis	city	feminine
silva, silvae	forest	feminine
īnsula, īnsulae	island	feminine
templum, templī	temple	neuter
mūrus, mūrī	wall	masculine

Example sentences

• Puella ad vīllam ambulat. means "The girl walks to the farmhouse." ad takes the accusative for motion toward.
• Agricola in agrō labōrat. means "The farmer works in the field." in plus ablative marks place where.
• Nautae ex īnsulā nāvigant. means "The sailors sail from the island." ex takes the ablative.
• Mīlitēs prō patriā pugnant. means "The soldiers fight for their homeland." prō takes the ablative.
• Fēmina per silvam ad oppidum ambulat. means "The woman walks through the forest to the town." Two accusative prepositions in a row.

Worked example

Translate Nauta cum amīcō ad oppidum ambulat. Break it down: nauta (nominative, subject) "the sailor"; cum amīcō (cum plus ablative) "with a friend"; ad oppidum (ad plus accusative) "to the town"; ambulat "walks". Result: "The sailor walks to the town with a friend."

Notice how each preposition pulled its noun into the right case, one ablative and one accusative. When you read, treat a preposition as a signal that the next noun belongs to it, then bundle the two as a single phrase.

How to build it: stacking phrases

Translate "The soldiers hurry across the road into the temple." Subject: mīlitēs, nominative plural. First phrase: across takes the accusative, trāns viam. Second phrase: "into" is motion, so in plus accusative, in templum. Verb: they hurry, properant, last. Assemble: Mīlitēs trāns viam in templum properant. Now change one idea, "the soldiers wait in the temple": rest, not motion, so the case flips to ablative, Mīlitēs in templō manent. Same preposition, different ending, different picture. Choosing the case is not bookkeeping; it is the meaning.

Reading: an evening walk

Read the passage aloud, then check the translation and the case notes.

Mārcus et amīcī ex oppidō ambulant. Per silvam ad vīllam properant. In vīllā cēnant, quod nox est. Prope vīllam est hortus magnus, ubi rosae sunt.

Translation: "Marcus and his friends walk out of the town. Through the forest they hurry to the farmhouse. In the farmhouse they dine, because it is night. Near the farmhouse is a large garden, where there are roses."

Three notes. Trace the cases: ex oppidō and in vīllā are ablative, while per silvam, ad vīllam, and prope vīllam are accusative. The second sentence stacks two phrases before its verb, exactly like the build-it example. And the last sentence opens with prope vīllam est, the "there is" pattern from the sum lesson wearing a prepositional phrase in front.

A second worked example

Parse Servī sine dominō ex agrīs ad oppidum properant. Verb last, as usual: properant, "they hurry", 3rd plural. Subject: servī, nominative plural, "the slaves". Now bundle each preposition with its noun: sine dominō, ablative, "without the master"; ex agrīs, ablative plural, "out of the fields"; ad oppidum, accusative, "to the town". Result: "Without the master, the slaves hurry out of the fields to the town." Three prepositional phrases stacked in a row, each self-contained because its case is sealed inside it; that stacking is exactly how longer Latin sentences grow, and the bundling habit keeps them readable.

Latin phrases English never returned

Because preposition-plus-case bundles are so compact, English borrowed them whole and still uses them daily. Post scriptum, "written after", is the P.S. at the bottom of a letter; ante bellum, "before the war", names an era of American history; per capita is "by heads"; prō bonō is short for prō bonō pūblicō, "for the public good"; a subpoena summons you "under penalty" (sub poenā); and dē factō means "from the fact", in practice. Each one is a preposition governing exactly the case this lesson taught, frozen in English amber. When you decode sub plus ablative today, you are reading the inside of the word subpoena.

Common misconceptions

• The object of a preposition can be nominative. It cannot. It is accusative or ablative, never the subject case; "cum nauta bonus" is impossible Latin.
• Every preposition always takes one fixed case. A few, above all in and sub, take the accusative for motion but the ablative for rest.
• The word in always means "in". With the accusative it means "into"; only with the ablative does it mean "in" or "on".
• You can drop cum because the ablative alone means "with". For accompaniment you need cum plus the ablative; the bare ablative means "with" only as a means or instrument.
• ex and ē, or ab and ā, are different words. They are the same preposition, with the longer form used before a vowel.
• cum can govern the accusative when the noun is a person. Never; cum is strictly an ablative preposition: cum amīcō, cum puellā, cum rēge.

Recap

• A preposition governs a fixed case; its object is accusative or ablative, never nominative.
• Accusative prepositions lean toward motion and extent: ad, in (into), per, trāns, ante, post, prope, contrā.
• Ablative prepositions lean toward rest, source, and company: in (in/on), cum, ex, ab, sine, dē, prō, sub.
• in and sub take the accusative for motion but the ablative for rest: in aquam versus in aquā.
• Read a preposition as a flag: bundle it with the next noun and translate the pair as one phrase.
• English keeps these bundles alive in post scriptum, per capita, prō bonō, subpoena, and dē factō.

The big picture

You have built all the pieces: cases, declensions, verb tenses, the verb sum, adjectives, and prepositions. Now you assemble them into whole sentences. Two ideas make translation reliable: understanding Latin word order, and following a fixed method every time.

The reward is real reading. A Latin sentence is not a puzzle to be guessed at but a set of endings to be decoded in order. Once the method is a habit, the words fall into place almost on their own.

Typical Latin word order

Latin has a preferred order, even though endings let it vary. The subject tends to come first, the verb tends to come last, and objects and other words sit in the middle.

So a neutral sentence looks like Subject - Object - Verb: Puella rosam amat ("The girl loves the rose"). English, by contrast, prefers Subject - Verb - Object. This is why the Latin verb so often lands at the end and must be carried back to just after the subject when you translate into English. Genitives and adjectives usually stand next to their nouns, datives drift toward the front of the middle, and little words like nōn sit directly before what they deny.

Word order is flexible

Because the endings carry the grammar, a Roman author could reorder words for emphasis or style. Rosam puella amat means the same thing; fronting rosam merely stresses "the rose". Your reading must therefore depend on endings, not position. A word at the front is not automatically the subject, and a verb is not always the last word.

The edges of the sentence are the spotlight seats. First position marks the topic the writer leads with; last position, usually the verb's, lands with weight. Puella rosam amat is a plain statement; Rosam puella amat answers "which thing does she love?"; Amat puella rosam leads with the loving itself. All three are correct; each has its own accent. Poets stretch this freedom furthest, even separating an adjective from its noun for music, trusting the endings to keep the pair married.

Vocabulary: the small connecting words

These short, unchanging words knit sentences together and appear on almost every page. They do not decline, so learn them as fixed forms.

Latin	English	Type
et	and	conjunction
-que	and (attached to the second word)	enclitic conjunction
sed	but	conjunction
nōn	not	adverb
quod	because	conjunction
quoque	also, too	adverb
semper	always	adverb
nunc	now	adverb
ōlim	once, formerly	adverb

The little -que deserves a note: it means "and" but glues itself to the end of the second item. puer puellaque is "the boy and the girl". Rome's most famous abbreviation carries it: SPQR, Senātus Populusque Rōmānus, "the Senate and People of Rome", stamped on standards, coins, and even modern Roman manhole covers.

A method for translating

Use this checklist on every sentence, in this order:

1. Find the verb. Its ending gives you the person, number, and tense. Often the verb is last.
2. Find the subject. Look for a nominative noun, or take the subject from the verb ending (a -t verb implies "he, she, or it").
3. Find the object. Look for an accusative noun that the verb acts on.
4. Attach the extras. Match adjectives to their nouns by agreement, bundle each preposition with its noun, and read datives as "to/for" and genitives as "of".
5. Render smooth English in the natural Subject - Verb - Object order.

The order of these steps matters. The verb anchors the whole sentence, giving you the action and often the subject through its ending. Once the verb and subject are fixed, every other word finds its place around them. Reaching for the first word instead of the verb is the most common beginner mistake.

Worked example 1

Agricola bonus filiam amat.

1. Verb: amat means "loves" (present, 3rd singular).
2. Subject: agricola (nominative) "the farmer"; the adjective bonus is masculine nominative, agreeing with the masculine noun, so "the good farmer".
3. Object: filiam (accusative) "the daughter".
4. Result: "The good farmer loves his daughter."

Worked example 2

In silva feminae ambulabant.

1. Verb: ambulabant; the -ba- marks the imperfect and -nt marks 3rd plural, so "they were walking".
2. Subject: feminae, nominative plural here, "the women".
3. Prepositional phrase: in silva, in plus ablative, "in the forest".
4. Result: "The women were walking in the forest."

Worked example 3

Poeta amicis fabulas narrabit.

1. Verb: narrabit; the -bi- marks the future and -t marks 3rd singular, so "he will tell".
2. Subject: poeta (nominative) "the poet".
3. Dative: amicis (dative plural) "to his friends"; object: fabulas (accusative plural) "stories".

Worked example 4

Fīlia rēgīnae rosās puellīs dat.

1. Verb: dat means "gives" (present, 3rd singular).
2. Subject: fīlia (nominative) "the daughter"; rēgīnae is genitive, "of the queen", so together "the queen's daughter".
3. Object and recipient: rosās (accusative plural) "roses"; puellīs (dative plural) "to the girls".
4. Result: "The queen's daughter gives roses to the girls."

Reading real Latin: the first words of the Aeneid

Your method already opens the door to genuine literature. Vergil's epic, the Aeneid, begins:

Arma virumque canō.

Apply the checklist. The verb is canō, first conjugation, 1st singular: "I sing (of)". No nominative noun appears, so the subject lives in the ending: the poet himself. Arma is a neuter accusative plural, "arms, weapons", and virum is accusative singular, "the man", with -que gluing the two objects together: "arms and the man". Result: "I sing of arms and the man." Three Latin words, an object pair, an enclitic, and a verb ending carrying the subject; every tool came from this course. The famous verb-last habit is even reversed here, because the poet wanted arma standing first in the whole epic, in the spotlight seat.

Reading: putting it all together

Read the passage aloud, then translate it with the method above before checking the English.

Iūlia est puella Rōmāna. Cum amīcīs in hortō saepe ambulat. Hodiē Iūlia rosās pulchrās spectat et fābulam nārrat. Amīcae laetae sunt. Crās puellae ad templum ambulābunt.

Translation: "Julia is a Roman girl. She often walks in the garden with her friends. Today Julia looks at the beautiful roses and tells a story. Her friends are happy. Tomorrow the girls will walk to the temple."

Three notes. The passage sweeps across the whole course: est and sunt from sum, the present verbs spectat and nārrat, and the future ambulābunt. Agreement appears in rosās pulchrās (feminine accusative plural) and the predicate laetae. And the prepositions behave exactly by their cases: cum amīcīs ablative, ad templum accusative.

One more passage, on your own

Translate this final passage completely before reading the version below. Every form comes from Lessons 1 through 13.

Ōlim rēx bonus in magnā urbe habitābat. Cīvēs rēgem amābant, quod iūstus erat. Rēx fīliae parvae fābulās saepe nārrābat. Post bellum pāx erat, et populus laetus erat. Semper in patriā nostrā pācem amābimus.

Version: "Once a good king lived in a great city. The citizens loved the king, because he was just. The king often used to tell stories to his small daughter. After the war there was peace, and the people were happy. We will always love peace in our homeland." If your translation matched in substance, you have completed the arc of the course: five declensions, three tenses, sum, agreement, prepositions, and the reading method, all working together.

Common misconceptions

• Word order decides subject and object in Latin. The endings decide; order signals emphasis and style.
• The verb is always the last word. It tends to come last, but authors move it for effect, so find it by its ending.
• You should translate word by word in the Latin order. Parse the endings first, then render natural English in Subject - Verb - Object order; word-by-word output produces "the good farmer the daughter loves".
• A word at the front must be the subject. A fronted accusative is still the object; always check the ending.
• Every noun needs a preposition to show its role. The case ending alone often carries the role; prepositions add place and direction.
• Small words can be skipped. The connectives steer the logic: sed pivots, quod explains, -que joins. Miss them and the sentences stop talking to each other.

Recap

• Neutral Latin order is Subject - Object - Verb, with genitives and adjectives beside their nouns.
• Order is flexible for emphasis; the sentence edges carry the spotlight, and endings always outrank position.
• Translate by method: verb first, then subject, object, extras, and finally smooth English.
• -que attaches to the second item to mean "and", as in SPQR, Senātus Populusque Rōmānus.
• The method reads real literature on day one: Arma virumque canō, "I sing of arms and the man".
• You now command the five declensions, three tenses, sum, agreement, and prepositions together.
