Through Verb and Grammatical tense

Thus verbs can take any of over 100 different endings to express different meanings, for example regō "I rule", regor "I am ruled", regere "to rule", regī "to be ruled". Most verbal forms consist of a single word, but some tenses are formed from part of the verb sum "I am" added to a participle; for example, ductus sum "I was led" or ductūrus est "he is going to lead".

Nouns belong to one of three grammatical genders (masculine, feminine, and neuter). The gender of the noun is shown by the last syllables of the adjectives, numbers and pronouns that refer to it: e.g. hic vir "this man", haec fēmina "this woman", hoc bellum "this war". There are also two numbers: singular (mulier "woman") and plural (mulierēs "women").

As well as having gender and number, nouns, adjectives, and pronouns have different endings according to their function in the sentence, for example, rēx "the king" (subject), but rēgem "the king" (object). These different endings are called "cases". Most nouns have five cases: nominative (subject or complement), accusative (object), genitive ("of"), dative ("to" or "for"), and ablative ("with", "in", "by" or "from"). Nouns for people (potential addressees) have the vocative (used for addressing someone). Some nouns for places have a seventh case, the locative; this is mostly found with the names of towns and cities, e.g. Rōmae "in Rome". Adjectives must agree with their nouns in gender, number, and case.

When a noun or pronoun is used with a preposition, the noun must be in either the accusative or the ablative case, depending on the preposition. Thus ad "to, near" is always followed by an accusative case, but ex "from, out of" is always followed by an ablative. The preposition in is followed by the ablative when it means "in, on", but by the accusative when it means "into, onto".

There is no definite or indefinite article in Latin, so that rēx can mean "king", "a king", or "the king" according to context.

Latin word order tends to be subject–object–verb; however, other word orders are common. Different word orders are used to express different shades of emphasis. (See Latin word order.)

An adjective can come either before or after a noun, e.g. vir bonus or bonus vir "a good man", although some kinds of adjectives, such as adjectives of nationality (vir Rōmānus "a Roman man") usually follow the noun.

Latin is a pro-drop language; that is, pronouns in the subject are usually omitted except for emphasis, so for example amās by itself means "you love" without the need to add the pronoun tū "you". Latin also exhibits verb framing in which the path of motion is encoded into the verb rather than shown by a separate word or phrase. For example, the Latin verb exit (a compound of ex and it) means "he/she/it goes out".

In this article a line over a vowel used on ā, ē, ī, ō, ū and ȳ is called a macron and it indicates that it is long.

Nouns

Number

Most Latin nouns have two numbers, singular and plural: rēx "king", rēgēs "kings". A few nouns, called plūrālia tantum ("plural only"), although plural in form, have a singular meaning, e.g. castra "a camp", litterae "a letter", nūptiae "a wedding".

Gender

Nouns are divided into three genders, known as masculine, feminine, and neuter. The difference is shown in the pronouns and adjectives that refer to them, for example:

  • ipse rēx "the king himself" (masculine)
  • ipsa rēgīna "the queen herself" (feminine)
  • ipsum bellum "the war itself" (neuter)

To a certain extent, the genders follow the meanings of the words (for example, winds are masculine, tree-names feminine):

  • Masculine nouns include all those referring to males, such as dominus "master", puer "boy", deus "god", but also some inanimate objects such as hortus "garden", exercitus "army", mōs "custom". Words in the 2nd declension ending in -us or -er are usually masculine.
  • Feminine nouns include all those referring to females, such as puella "girl", mulier "woman", dea "goddess", but also inanimate or abstract nouns such as arbor "tree", urbs "city", hūmānitās "kindness", nātiō "nation". Words in the 1st declension like puella ending in -a are usually feminine, with a few exceptions such as poēta "poet". Also feminine are 3rd declension nouns ending in -tās and -tiō.
  • Neuter nouns (apart from scortum "a prostitute (of either gender)") all refer to things, such as nōmen "name", corpus "body", bellum "war", venēnum "poison".

Neuter nouns differ from masculine and feminine in two ways: (1) the plural nominative and accusative forms end in -a, e.g. bella "wars", corpora "bodies"; (2) the subject (nominative) and object (accusative) cases are identical.

Case

Nouns in Latin have a series of different forms, called cases of the noun, which have different functions or meanings. For example, the word for "king" is rēx when it is the subject of a verb, but rēgem when it is the object:

  • rēx videt "the king sees" (nominative case)
  • rēgem videt "(he) sees the king" (accusative case)

Further cases mean "of" (genitive case), "to/for" (dative case), and "with" (ablative case).

Nouns for people have a separate form used for addressing a person (vocative case). In most nouns for women and girls, the vocative is the same as the nominative.

Some nouns, such as the names of cities and small islands, and the word domus "home", have a seventh case called the locative, for example Rōmae "in Rome" or domī "at home"; however, most nouns do not have this case.

The genitive, dative and ablative cases are called the "oblique" cases.

The order in which the cases are given in grammar books differs in different countries. In Britain and countries influenced by Britain, the order nominative, vocative, accusative is used as in the table below. In the United States, in grammars such as Gildersleeve and Lodge's Latin Grammar (1895), the traditional order is used, with the genitive case in the second place and ablative last. In the popularly used Wheelock's Latin (1956, 7th edition 2011) and Allen and Greenough's New Latin Grammar (1903), however, the vocative is placed at the end.

The following table shows the endings of a typical noun of the 3rd declension. If Gildersleeve and Lodge's order is preferred, click on the symbol "GL" in the seventh column in the table below; for Wheelock's order click on "Wh":

Sometimes the same endings, e.g. -ēs and -ibus, are used for more than one case. Since the function of a word in Latin is shown by ending rather than word order, in theory rēgēs dūcunt could mean either "the kings lead" or "they lead the kings". In practice, however, such ambiguities are rare.

Declensions

1st and 2nd declensions

Latin nouns are divided into different groups according to the patterns of their case endings. These different groups are known as declensions. Nouns with -a in the nominative singular, like puella "girl", are known as "1st declension nouns", and so on.

The following table shows the declension of puella "girl" (1st declension), dominus "lord, master" (2nd declension masculine), and bellum "war" (2nd declension neuter):

1st declension nouns are usually feminine, except for a few referring to men, such as agricola "farmer" or poēta "poet". The nouns fīlia "daughter" and dea "goddess" have dative and ablative plural fīliābus, deābus. The locative case ends in -ae, pl. -īs, e.g. Rōmae "in Rome", Athēnīs "in Athens".

2nd declension nouns in -us are usually masculine, but those referring to trees (e.g. pīnus "pine tree") and some place names (e.g. Aegyptus "Egypt") are feminine. A few 2nd declension nouns, such as vir "man" and puer "boy", lack endings in the nominative and vocative singular. In the 2nd declension, the genitive plural in some words is optionally -um, especially in poetry: deum or deōrum "of the gods", virum or virōrum "of men".

Neuter nouns such as bellum "war" have -a in the nominative plural. In neuter nouns, the vocative and accusative are always the same as the nominative; the genitive, dative, and ablative are the same as the masculine. Most 2nd declension neuter nouns end in -um but vīrus "poison" and vulgus "crowd" end in -us.

3rd declension

Third declension nouns have various patterns of declension. Some decline like the following: mīles "soldier", urbs "city", corpus "body":

There are some variations, however. A few, such as vīs, vim, vī "force", have accusative singular -im and ablative singular -ī; some, like ignis "fire", optionally have -ī instead of -e in the ablative singular. The genitive plural in some nouns is -um, in others -ium. (For details, see Latin declension.) 3rd declension nouns can be of any gender.

It is not usually possible to guess the genitive of a noun from the nominative: dux "leader" has genitive ducis but rēx "king" has rēgis; pater "father" has genitive patris but iter "journey" has itineris. For this reason the genitive is always given in dictionaries, and can be used to deduce the remaining cases.

4th and 5th declensions

4th and 5th declension nouns are less common. They decline like the following (manus "hand", genū "knee", diēs "day"):

4th declension nouns are usually masculine, but a few, such as manus "hand" and anus "old lady", are feminine. There are only four 4th declension neuter nouns.

5th declension nouns (except for diēs (m) "day") are usually feminine. rēs "thing" is similar to diēs except for a short e in the genitive and dative singular reī.

Other nouns

In addition to the above there are some irregularly declined nouns, mostly borrowed from Greek, such as the name Aenēās "Aeneas" (1st declension masculine).

The vocative is nearly always the same as the nominative, except in 1st and 2nd declension masculine singular words, such as Aenēā! "Aeneas!" and domine! "master!/lord!". Some words, such as deus "god", have no separate vocative, however.

Use of cases

Nominative

The nominative case is used for the subject of an active or a passive verb:

rēx respondit = the king replied
rēx occīsus est = the king was killed

It is also used for the complement of a copula verb such as est "he is" or factus est "he became":

rēx erat Aenēās nōbīs = our king was Aeneas / Aeneas was our king
rēx factus est = he was made king / he became king

Vocative

The vocative case is used when addressing someone:

iubēsne mē, Rōmule Rēx, foedus ferīre? = do you order me, King Romulus, to strike a treaty?

Accusative

The accusative case is used for the object of a sentence:

rēgem interfēcērunt = they killed the king

It is also used as the subject of an infinitival clause dependent on a verb of speaking or the like:

rēgem interfectum esse crēdēbant = they believed that the king had been killed

It can be the complement of another word which is itself accusative:

Tullum populus rēgem creāvit = the people made Tullus their king

It can also be used with a place name to refer to the destination:

Rōmam profectus est = he set out for Rome

The accusative is also used after various prepositions (especially those that imply motion towards):

senātus ad rēgem lēgātōs mīsit = the Senate sent ambassadors to the king
cōnsul in urbem rediit = the consul returned to the city

Another use of the accusative is to give a length of time or distance:

rēgnāvit annōs quīnque = he reigned for five years
quīnque pedēs longus = five foot tall

Genitive

A genitive noun can represent possession or relationship:

rēgis fīlia = the king's daughter, daughter of the king

A genitive noun can stand for the object of mental processes such as misereor "I pity" and oblīvīscor "I forget":

numquam oblīvīscar noctis illīus = I will never forget that night

A genitive noun attached to a verbal noun can stand for the object of the implied verb (called an "objective genitive"):

maximī virī dēsiderium = my longing for the great man

A genitive noun can stand for the subject of the implied verb (called a "subjective" genitive):

Caesaris adventus = Caesar's arrival

A frequent type of genitive is the partitive genitive, expressing the quantity of something:

satis temporis = enough time

Dative

The dative case means "to" or "for". It is frequently used with verbs of saying or giving:

rēgī nūntiātum est = it was announced to the king
pecūniam rēgī crēdidit = he entrusted the money to the king

It can also be used with certain adjectives:

cārissimus erat rēgī = he was very dear to the king

It is also used with certain verbs such as pāreō "I obey" or persuādeō "I persuade":

pāruit rēgī = he was obedient to (i.e. obeyed) the king

There are also various idiomatic uses, such as the dative of possession:

quid est tibī nōmen? = what's your name?

Ablative

The ablative case can mean "with", especially when the noun it refers to is a thing rather than a person:

gladiō sē transfīgit = he stabbed himself with a sword

Often a phrase consisting of a noun plus participle in the ablative can express time or circumstance. This is known as an "ablative absolute":

rēgibus exāctīs = with the kings driven out, i.e. after the kings were driven out

It is also frequently used with prepositions, especially those meaning "from", "with", "in", or "by":

ūnus ē rēgibus = one from (i.e. one of) the kings
cum rēgibus = with the kings
ā rēgibus = by the kings, from the kings
prō rēge = for/on behalf of the king

Another use is in expressions of time and place (except those that give the length of time or distance):

eō tempore = at that time
hōc locō = at this place
paucīs diēbus = in a few days

The ablative can also mean "from", especially with place names:

Rōmā profectus est = he set out from Rome
locō ille mōtus est = he was dislodged from his position

Locative

The locative is a rare case used only with names of cities, small islands, and one or two other words such as domus "home". It means "at" or "in":

cōnsul alter Rōmae mānsit = one of the two consuls remained in Rome
multōs annōs nostrae domī vīxit = he lived at our house for many years
