Latin grammar

Latin is an old language that has special ways of changing words to show their meaning. Words can change their endings to show if they are the subject or object of a sentence, or even if they are describing something else. This helps people understand the sentence better even when the words are not in the usual order.

For example, the word for "king" can change to show if it is doing the action, receiving the action, or being talked about. Nouns in Latin also have genders—masculine, feminine, or neuter—and they can be singular or plural. This means a word might change depending on whether it is talking about one man or many women, and whether it is being described as a subject or an object.

Latin does not use words like "the" or "a" before nouns, so the meaning of a word like "king" depends on the context. The order of words in a Latin sentence can also change to show emphasis or focus. Even the small details, like how long a vowel sound is, can change the meaning of a word. These rules help us understand Latin texts from long ago and see how the language works.

Nouns

Latin nouns can change their endings to show different meanings. There are two numbers: singular, which means one, and plural, which means more than one. For example, rēx means "king" and rēgēs means "kings".

Nouns also have three genders: masculine, feminine, and neuter. This affects the words that describe them. For example, ipse rēx means "the king himself" (masculine), ipsa rēgīna means "the queen herself" (feminine), and ipsum bellum means "the war itself" (neuter).

Nouns change their endings to show their role in a sentence. For example, rēx means "the king" when it is the subject, and rēgem means "the king" when it is the object. Different endings can also show relationships like "of", "to", or "with".

Latin nouns are grouped into different declensions based on their patterns of changing endings. These groups help us understand how the nouns change in different roles.

Adjectives

Adjectives in Latin, like nouns, change their endings depending on their case, number, and gender. They can be masculine, feminine, or neuter, and have different forms for singular and plural. Many adjectives follow the same patterns as certain nouns.

Adjectives also change to match the noun they describe. This means they must have the same case, number, and gender as the noun. For example, if a noun is in the vocative case, the adjective describing it must also be in the vocative case.

Adjectives can have different levels of comparison, such as positive (basic form), comparative (more), and superlative (most). Comparative adjectives often follow special patterns, while superlative adjectives usually follow the first and second declension patterns.

Pronouns

Pronouns in Latin come in two types: personal pronouns and third-person pronouns. Personal pronouns change their endings depending on who or what they refer to. For example, mē means "me" and tē means "you."

Third-person pronouns are words like hic, meaning "this," and ipse, meaning "himself." These pronouns can also act like describing words. Their endings change in special ways, and some have unique forms. Common third-person pronouns include hic, haec, hoc meaning "this" and is, ea, id meaning "he, she, it; that." These can stand alone or describe a noun.

Pronouns, like describing words, must match the gender, case, and number of the nouns they refer to. Latin does not use words like "the" or "a" before nouns, but sometimes is, ea, id can act like "that" or "this" in English.

Adverbs

Adverbs describe how, when, or where something happens. In Latin, adverbs do not change form—they stay the same no matter how they are used. They can describe things like time, place, or manner, just like in English.

Adverbs can be made from adjectives. For example, the adjective "bright" can become the adverb "brightly." Some endings used to make adverbs are -ē, -(t)er, -ō, -e, and -tim. The comparative form of an adverb, like "more brightly," often ends in -ius. The superlative form, like "very brightly" or "most brightly," usually ends in a long -ē.

Prepositions

A prepositional phrase in Latin is made up of a preposition followed by a noun phrase. The preposition decides which form of the noun to use. For example, the word in uses one form when it means "into" and another when it means "on" or "inside":

in urbem = "into the city"

in urbe = "in the city"

Most prepositions use only one form. For example, those that mean "from", "by", or "with" use a special form called the ablative:

ex urbe = "out of the city"

ab urbe = "(away) from the city"

cum Caesare = "with Caesar"

Other prepositions use only another form called the accusative:

extrā urbem = "outside the city"

ad urbem = "to/near the city"

per urbem = "through(out) the city"

circum urbem = "around the city"

There are also a few postpositions. tenus "as far as" usually follows a special form, sometimes another form:

Taurō tenus "as far as Taurus"

Cūmārum tenus "as far as Cumae"

versus "towards" is usually combined with ad or in:

ad Alpēs versus "towards the Alps"

causā "for the sake of" follows another form:

honōris causā "for the sake of (doing) honour"

The word cum "with" is usually a preposition, but with certain words it follows and joins with them in writing:

cum eō "with him"

mēcum "with me"

Both quōcum and cum quō "with whom" are found.

Numerals and numbers

Main article: Latin numerals

Latin has special words for numbers. The numbers one, two, and three change form depending on whether they are used with male, female, or neutral nouns. For example, "one camp" is ūna castra and "one letter" is ūnae litterae.

Numbers from four to ten do not change form. Larger numbers have their own special words, and when we count up to twenty or more, we use different patterns. For example, twenty-one can be said as vīgintī ūnus or ūnus et vīgintī. The number one thousand is mille, and for larger numbers like two thousand, we say duo mīlia.

Verbs

Latin verbs change their endings to show who is doing the action, how many people are involved, and what kind of action it is. There are three people in the singular — "I", "you", and "he/she/it" — and three in the plural — "we", "you all", and "they". Unlike some other languages, Latin does not have special forms for talking to someone important; the same "you" is used for everyone.

Most verbs do not change based on whether the subject is male or female. However, when a verb is built using a participle and the verb "to be", the participle shows the gender. For example, "he was sent" and "she was sent" use different endings.

Latin verbs have two voices: active and passive. An active verb says "I lead", while a passive verb says "I am led". Some verbs look like passive verbs but have an active meaning, such as "I follow".

Latin verbs also have different moods, which show the type of statement being made. The indicative mood is used for ordinary statements like "I lead" or "he came". The subjunctive mood is used for possibilities, wishes, and certain types of clauses, like "he may lead". The imperative mood is used for commands, like "lead!".

Latin verbs have several tenses, including present, past, and future. These tenses help show when an action happens. There are also special forms called participles and infinitives that do not show tense clearly but are used in other ways.

Different groups of verbs follow slightly different patterns, called conjugations. Most verbs are regular and follow one of five main patterns. Some verbs, like "I am", are irregular and have their own special patterns.

Word order

Main article: Latin word order

Latin has very flexible word order because of its special way of changing words to show meaning. In everyday writing, Latin usually followed the pattern of subject, then direct object, then indirect object, then any describing words, and finally the verb. Extra verbs, like those showing purpose, usually came before the main verb. Describing words and parts of verbs typically came right after the nouns they described, except for words about beauty, size, amount, goodness, or truth, which often came before the noun.

In Latin, the order of words in a sentence didn’t change the meaning because the meaning was shown by changing the endings of words, not their position. This meant writers could change the order of words to give different feelings or emphasis without making the sentence hard to understand.

In everyday spoken Latin, the most common order was probably subject, object, then verb. This pattern can still be seen in some modern languages that came from Latin, like Sardinian and Sicilian, where the verb often comes at the end of the sentence. But in ancient Latin conversation, the order of subject, verb, then object was also common and is a pattern in many Romance languages.

In poetry, writers often changed the word order to fit the rhythm of the poem. Since Roman poets performed their work by speaking it aloud, changing word order helped make the poem sound better and also served to emphasize certain words.

For example, in the poet Virgil’s work Eclogues, he wrote, “Omnia vincit amor, et nōs cēdāmus amōrī!” which means “Love conquers all, let us too yield to love!” The words “all,” “love,” and “to love” stand out because they are placed in unusual positions in the sentence.

The ending of the common Roman name “Mārcus” changes depending on its role in the sentence. Here are some examples:

Mārcus ferit Cornēliam: Marcus hits Cornelia. (subject–verb–object)

Mārcus Cornēliam ferit: Marcus Cornelia hits. (subject–object–verb)

Cornēlia dedit Mārcō dōnum: Cornelia gave Marcus a gift. (subject–verb–indirect object–direct object)

Cornēlia Mārcō dōnum dedit: Cornelia (to) Marcus a gift gave. (subject–indirect object–direct object–verb)
