[[Latin]] is a heavily [[inflected languages|inflected language]] with largely [[free word order]]. [[Noun]]s are inflected for [[grammatical number|number]] and [[grammatical case|case]]; [[pronoun]]s and [[adjective]]s (including [[participle]]s) are inflected for number, case, and [[grammatical gender|gender]]; and [[verb]]s are inflected for [[grammatical person|person]], number, [[grammatical tense|tense]], [[grammatical aspect|aspect]], [[grammatical voice|voice]], and [[grammatical mood|mood]]. The inflections are often changes in the ending of a word, but can be more complicated, especially with verbs.

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

Nouns belong to one of three [[grammatical gender|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. {{lang|la|hic vir}} "this man", {{lang|la|haec fēmina}} "this woman", {{lang|la|hoc bellum}} "this war". There are also two [[grammatical number|numbers]]: singular ({{lang|la|mulier}} "woman") and plural ({{lang|la|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, {{lang|la|rēx}} "the king" (subject), but {{lang|la|rēgem}} "the king" (object). These different endings are called "cases". Most nouns have five cases: [[Nominative case|nominative]] (subject or [[complement (linguistics)|complement]]), [[Accusative case|accusative]] (object), [[Genitive case|genitive]] ("of"), [[Dative case|dative]] ("to" or "for"), and [[Ablative case|ablative]] ("with", "in", "by" or "from"). Nouns for people (potential addressees) have the [[Vocative case|vocative]] (used for addressing someone). Some nouns for places have a seventh case, the [[Locative case|locative]]; this is mostly found with the names of towns and cities, e.g. {{lang|la|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 {{lang|la|ad}} "to, near" is always followed by an accusative case, but {{lang|la|ex}} "from, out of" is always followed by an ablative. The preposition {{lang|la|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 (grammar)|article]] in Latin, so that {{lang|la|rēx}} can mean "king", "a king", or "the king" according to context.

The scene is an allegory of grammar and, by implication, all of education. Note the opening door in the background and the unshod feet of the first pupil.]]

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. {{lang|la|vir bonus}} or {{lang|la|bonus vir}} "a good man", although some kinds of adjectives, such as adjectives of nationality ({{lang|la|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 {{lang|la|amās}} by itself means "you love" without the need to add the pronoun {{lang|la|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 {{lang|la|exit}} (a compound of '''{{wikt-lang|la|ex}}''' and {{wikt-lang|la|eo|it}}) means "he/she/it goes out".

In this article a [[Macron (diacritic)|line over a vowel]] (e.g. ē) indicates that it is [[Vowel length|long]].

==Nouns==
===Number===
Most Latin nouns have two numbers, singular and plural: {{lang|la|rēx}} "king", {{lang|la|rēgēs}} "kings". A few nouns, called {{lang|la|plūrālia tantum}} ("plural only"), although plural in form, have a singular meaning, e.g. {{lang|la|castra}} "a camp", {{lang|la|litterae}} "a letter", {{lang|la|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:
*{{lang|la|'''ipse rēx'''}} "the king himself" (''masculine'')
*{{lang|la|'''ipsa rēgīna'''}} "the queen herself" (''feminine'')
*{{lang|la|'''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 {{lang|la|dominus}} "master", {{lang|la|puer}} "boy", {{lang|la|deus}} "god", but also some inanimate objects such as {{lang|la|hortus}} "garden", {{lang|la|exercitus}} "army", {{lang|la|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 {{lang|la|puella}} "girl", {{lang|la|mulier}} "woman", {{lang|la|dea}} "goddess", but also inanimate or abstract nouns such as {{lang|la|arbor}} "tree", {{lang|la|urbs}} "city", {{lang|la|hūmānitās}} "kindness", {{lang|la|nātiō}} "nation". Words in the 1st declension like {{lang|la|puella}} ending in ''-a'' are usually feminine, with a few exceptions such as {{lang|la|poēta}} "poet". Also feminine are 3rd declension nouns ending in ''-tās'' and ''-tiō''.
*'''Neuter''' nouns (apart from {{lang|la|scortum}} "a prostitute (of either gender)") all refer to things, such as {{lang|la|nōmen}} "name", {{lang|la|corpus}} "body", {{lang|la|bellum}} "war", {{lang|la|venēnum}} "poison".

Neuter nouns differ from masculine and feminine in two ways: (1) the plural nominative and accusative forms end in ''-a'', e.g. {{lang|la|bella}} "wars", {{lang|la|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 {{lang|la|rēx}} when it is the subject of a verb, but {{lang|la|rēgem}} when it is the object:
*{{lang|la|rēx videt}} "the king sees" (nominative case)
*{{lang|la|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 {{lang|la|domus}} "home", have a seventh case called the '''locative''', for example {{lang|la|Rōmae}} "in Rome" or {{lang|la|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.{{sfn|Kennedy|1962|p=13}} 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.{{sfn|Kennedy|1962|p=22}} 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. {{lang|la|-ēs}} and {{lang|la|-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 {{lang|la|rēgēs dūcunt}} could mean either "the kings lead" or "they lead the kings". In practice, however, such ambiguities are rare.

===Declensions===
{{Main|Latin declension}}

====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 {{lang|la|puella}} "girl" are known as ''1st declension nouns'', and so on.

The following table shows the declension of {{lang|la|puella}} "girl" (1st declension), {{lang|la|dominus}} "lord, master" (2nd declension masculine), and {{lang|la|bellum}} "war" (2nd declension neuter):{{sfn|Kennedy|1962|pp=17-19}}

1st declension nouns are usually feminine, except for a few referring to men, such as {{lang|la|agricola}} "farmer" or {{lang|la|poēta}} "poet". The nouns {{lang|la|fīlia}} "daughter" and {{lang|la|dea}} "goddess" have dative and ablative plural {{lang|la|fīliābus, deābus}}. The locative case ends in ''-ae'', pl. ''-īs'', e.g. {{lang|la|Rōmae}} "in Rome", {{lang|la|Athēnīs}} "in Athens".{{sfn|Kennedy|1962|p=17}}

2nd declension nouns in ''-us'' are usually masculine, but those referring to trees (e.g. {{lang|la|pīnus}} "pine tree") and some place names (e.g. {{lang|la|Aegyptus}} "Egypt") are feminine. A few 2nd declension nouns, such as {{lang|la|vir}} "man" and {{lang|la|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:{{sfn|Allen|Greenough|Kittredge|Howard|1903|loc=§49}}{{sfn|Kennedy|1962|p=19}} {{lang|la|deum}} or {{lang|la|deōrum}} "of the gods", {{lang|la|virum}} or {{lang|la|virōrum}} "of men".

Neuter nouns such as {{lang|la|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 {{lang|la|vīrus}} "poison" and {{lang|la|vulgus}} "crowd" end in ''-us''.

====3rd declension====
Third declension nouns have various patterns of declension. Some decline like the following: {{lang|la|mīles}} "soldier", {{lang|la|urbs}} "city", {{lang|la|corpus}} "body":{{sfn|Kennedy|1962|p=22-26}}

|}

There are some variations, however. A few, such as {{lang|la|vīs, vim, vī}} "force", have accusative singular ''-im'' and ablative singular ''-ī''; some, like {{lang|la|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: {{lang|la|dux}} "leader" has genitive {{lang|la|ducis}} but {{lang|la|rēx}} "king" has {{lang|la|rēgis}}; {{lang|la|pater}} "father" has genitive {{lang|la|patris}} but {{lang|la|iter}} "journey" has {{lang|la|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 ({{lang|la|manus}} "hand", {{lang|la|genū}} "knee", {{lang|la|diēs}} "day"):{{sfn|Kennedy|1962|p=30-31}}

4th declension nouns are usually masculine, but a few, such as {{lang|la|manus}} "hand" and {{lang|la|anus}} "old lady", are feminine. There are only four 4th declension neuter nouns.{{sfn|Allen|Greenough|Kittredge|Howard|1903|loc= §91}}

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

====Other nouns====
In addition to the above there are some irregularly declined nouns, mostly borrowed from Greek, such as the name {{lang|la|Aenēās}} "Aeneas" (1st declension masculine).{{sfn|Kennedy|1962|p=34-36}}

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

===Use of cases===
{{Further|Latin syntax#Examples of case use}}

====Nominative====
The [[nominative]] case is used for the [[Subject (grammar)|subject]] of an [[Active voice|active]] or a [[Passive voice|passive]] verb:
:{{lang|la|'''rēx''' respondit}} = the king replied
:{{lang|la|'''rēx''' occīsus est}} = the king was killed

It is also used for the [[Complement (linguistics)|complement]] of a [[Copula (linguistics)|copula]] verb such as {{lang|la|est}} "he is" or {{lang|la|factus est}} "he became":{{sfn|Kennedy|1962|p=119}}
:{{lang|la|'''rēx''' erat Aenēās nōbīs}} = our king was Aeneas / Aeneas was our king
:{{lang|la|'''rēx''' factus est}} = he was made king / he became king

====Vocative====
The [[vocative]] case is used when addressing someone:
:{{lang|la|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:{{sfn|Kennedy|1962|pp=119-122}}
:{{lang|la|'''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:
:{{lang|la|'''rēgem''' interfectum esse crēdēbant}} = they believed that the king had been killed

It can be the complement of another word which is itself accusative:
:{{lang|la|'''Tullum''' populus '''rēgem''' creāvit}} = the people made Tullus their king

It can also be used with a place name to refer to the destination:
:{{lang|la|'''Rōmam''' profectus est}} = he set out for Rome

The accusative is also used after various prepositions (especially those that imply motion towards):
:{{lang|la|senātus ad '''rēgem''' lēgātōs mīsit}} = the Senate sent ambassadors to the king
:{{lang|la|cōnsul in '''urbem''' rediit}} = the consul returned to the city

Another use of the accusative is to give a length of time or distance:
:{{lang|la|rēgnāvit '''annōs''' quīnque}} = he reigned for five years
:{{lang|la|quīnque '''pedēs''' longus}} = five foot tall

====Genitive====
A [[genitive]] noun can represent possession or relationship:
:{{lang|la|'''rēgis''' fīlia}} = the king's daughter, daughter of the king

A genitive noun can stand for the object of mental processes such as {{lang|la|misereor}} "I pity" and {{lang|la|oblīvīscor}} "I forget":{{sfn|Gildersleeve|Lodge|1903|pp=240-242}}
:{{lang|la|numquam oblīvīscar '''noctis illīus'''}} = I will never forget that night<ref>Cicero, ''Planc.'' 101.</ref>

A genitive noun attached to a verbal noun can stand for the object of the implied verb (called an "objective genitive"):
:{{lang|la|maximī '''virī''' dēsiderium}} = my longing for the great man<ref>Pliny the Younger, ''Ep.'' 6.11.1.</ref>

A genitive noun can stand for the subject of the implied verb (called a "subjective" genitive):{{sfn|Gildersleeve|Lodge|1903|pp=232-233}}
:{{lang|la|'''Caesaris''' adventus}} = Caesar's arrival

A frequent type of genitive is the partitive genitive, expressing the quantity of something:{{sfn|Gildersleeve|Lodge|1903|pp=235-237}}
:{{lang|la|satis '''temporis'''}} = enough time

====Dative====
The [[dative]] case means "to" or "for". It is frequently used with verbs of saying or giving: 
:{{lang|la|'''rēgī''' nūntiātum est}} = it was announced to the king
:{{lang|la|pecūniam '''rēgī''' crēdidit}} = he entrusted the money to the king

It can also be used with certain adjectives:
:{{lang|la|cārissimus erat '''rēgī'''}} = he was very dear to the king<ref>Curtius, 3.12.16.</ref>

It is also used with certain verbs such as {{lang|la|pāreō}} "I obey" or {{lang|la|persuādeō}} "I persuade":{{sfn|Kennedy|1962|p=123-127}}
:{{lang|la|pāruit '''rēgī'''}} = he was obedient to (i.e. obeyed) the king

There are also various idiomatic uses, such as the dative of possession:
:{{lang|la|quid est '''tibī''' nōmen?}} = what's your name?<ref>Plautus, ''Pseudolus'' 634.</ref>

====Ablative====
The [[ablative]] case can mean "with", especially when the noun it refers to is a thing rather than a person:{{sfn|Kennedy|1962|p=128-132}}
:{{lang|la|'''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":{{sfn|Kennedy|1962|p=130}}
:{{lang|la|'''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":
:{{lang|la|ūnus ē '''rēgibus'''}} = one from (i.e. one of) the kings
:{{lang|la|cum '''rēgibus'''}} = with the kings
:{{lang|la|ā '''rēgibus'''}} = by the kings, from the kings
:{{lang|la|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):
:{{lang|la|'''eō tempore'''}} = at that time
:{{lang|la|'''hōc locō'''}} = at this place
:{{lang|la|'''paucīs diēbus'''}} = in a few days

The ablative can also mean "from", especially with place names:{{sfn|Kennedy|1962|p=128}}
:{{lang|la|'''Rōmā''' profectus est}} = he set out from Rome
:{{lang|la|'''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":{{sfn|Kennedy|1962|p=132}}
:{{lang|la|cōnsul alter '''Rōmae''' mānsit}} = one of the two [[consul]]s remained in Rome<ref>Livy, 2.33.4.</ref>
:{{lang|la|multōs annōs '''nostrae domī''' vīxit}} = he lived at our house for many years<ref>Cicero, ''Tusc. Disp.'' 5.113.</ref>

==Adjectives==
===Declension of adjectives===
Adjectives, like nouns, have different endings for the different cases, singular and plural. They also differ as to gender, having different forms for masculine, feminine, and neuter. (But masculine and neuter are identical in the genitive, dative, and ablative cases.)

Many adjectives belong to the 1st and 2nd declensions, declining in the same way as the nouns {{lang|la|puella, dominus, bellum}}. An example is the adjective {{lang|la|bonus}} "good" shown below:

{| class="wikitable sortable"

|-
|}

Other adjectives belong to the 3rd declension, in which case the masculine and feminine are usually identical. Most 3rd declension adjectives are i-stems, and have ablative singular ''-ī'' and genitive plural ''-ium''. An example is {{lang|la|ingēns}} "huge" shown below:

{| class="wikitable sortable" 
|-

|-
|}

In a very few 3rd declension adjectives such as {{lang|la|ācer, ācris, ācre}} "sharp, keen", the feminine is different from the masculine, but only in the nominative and vocative singular.

A few adjectives (especially comparative adjectives) decline as consonant stems, and have ablative singular ''-e'' and genitive plural ''-um''. An example is {{lang|la|melior}} "better":

{| class="wikitable sortable" 
|-

|-
|}

Participles such as {{lang|la|dūcēns}} "leading" usually have ''-e'' in the ablative singular, but ''-ium'' in the genitive plural.{{sfn|Gildersleeve|Lodge|1903|p=42}}

There are no adjectives in the 4th or 5th declensions.

The adjectives {{lang|la|sōlus}} "only" and {{lang|la|tōtus}} "the whole of" decline like pronouns, with genitive singular ''-īus'' and dative singular ''-ī'':
:{{lang|la|'''tōtīus''' Graeciae}} = of the whole of Greece (genitive case)
:{{lang|la|tibī '''sōlī'''}} = to you alone (dative case)

===Agreement of adjectives===
Any adjective that describes or refers to a noun must be in the same case as the noun, as well as the same number and gender. Thus in the phrase below, where ''rēx'' is in the vocative singular case, ''bonus'' must be in the vocative singular also:
:{{lang|la|ō '''bone''' rēx}} = o good king

===Comparative and superlative adjectives===
Adjectives have positive, comparative and superlative forms. Superlative adjectives are declined according to the first and second declension, but comparative adjectives are third declension.

When used in sentences, a comparative adjective can be used in several ways:
* Absolutely (with the meaning "rather" or "more than usual")
* With {{wikt-lang|la|quam}} (Latin for "than")
* With an ablative meaning "than"
* With the genitive

Examples:

* ''{{lang|la|Cornēlia est '''fortis''' puella}}'': Cornelia is a brave girl.

The comparative adjective can be used absolutely (i.e. without any overt comparison) or with the comparison made explicit:
* ''{{lang|la|Cornēlia est '''fortior''' puella}}'': Cornelia is a rather brave girl.
* ''{{lang|la|Cornēlia est '''fortior''' puella quam Flāvia}}'': Cornelia is a braver girl than Flavia. (Here ''quam'' is used, ''Flavia'' is in the nominative to match Cornelia)
* ''{{lang|la|Cornēlia est '''fortior''' Flāviā}}'': Cornelia is braver than Flavia. (Here ''Flavia'' is in the ablative.)
* ''{{lang|la|Cornēlia est '''fortior''' puellārum}}'': Cornelia is the braver of the girls

Superlative adjectives are most frequently used absolutely, but they can also be used with the genitive {{lang|la|omnium}} "of all":
* ''{{lang|la|Cornēlia est puella '''fortissima'''}}'': Cornelia is a very brave girl
* ''{{lang|la|Cornēlia est puella omnium '''fortissima'''}}'': Cornelia is the bravest girl of all.

{{lang|la|mē, tē, nōs, vōs}} can also be used reflexively ("I see myself" etc.).{{sfn|Allen|Greenough|Kittredge|Howard|1903|p=64}}

{{lang|la|Nōs}} is frequently used in classical Latin for "I", but {{lang|la|vōs}} is never used in a singular sense.{{sfn|Allen|Greenough|Kittredge|Howard|1903|p=63}}

The genitive {{lang|la|nostrum}} is used partitively ({{lang|la|ūnusquisque nostrum}} "each one of us"), {{lang|la|nostrī}} objectively ({{lang|la|memor nostrī}} "remembering us, mindful of us").{{sfn|Kennedy|1962|p=48}}{{sfn|Allen|Greenough|Kittredge|Howard|1903|p=64}}

3rd person pronouns are those such as {{lang|la|hic}} "this" and {{lang|la|ipse}} "(he) himself". The 3rd person pronouns can also be used adjectivally (except that {{lang|la|quid}} "what?" when adjectival becomes {{lang|la|quod}}). The declension of these pronouns tends to be irregular. They generally have ''-īus'' in the genitive singular, and ''-ī'' in the dative singular. In a few pronouns ({{lang|la|illud}} "that", {{lang|la|istud}} "that (of yours)", {{lang|la|id}} "it, that", {{lang|la|quod}} "which", {{lang|la|quid}} "anything; what?", {{lang|la|aliud}} "another", {{lang|la|aliquid}} "something") the neuter singular ends in ''-d''.

The declension of {{lang|la|ille}} "that" is as follows:{{sfn|Kennedy|1962|p=49}}

|-

{{lang|la|Ipse}} "he himself" is very similar, except that the neuter singular {{lang|la|ipsum}} ends in ''-m'' instead of ''-d''.

Other very common 3rd person pronouns are {{lang|la|hic, haec, hoc}} "this" and {{lang|la|is, ea, id}} "he, she, it; that". Like other 3rd person pronouns, these can be used either independently ({{lang|la|is}} "he") or adjectivally ({{lang|la|is homō}} "that man"):

Also very common is the relative pronoun {{lang|la|quī, quae, quod}} "who, which". The interrogative {{lang|la|quis? quid?}} "who? what?" and indefinite {{lang|la|quis, qua, quid}} "anyone, anything" are similar apart from the nominative singular:{{sfn|Kennedy|1962|p=51}}

Like adjectives, pronouns must agree in gender, case, and number with the nouns they refer to, as in the following, where ''hic'' is masculine agreeing with ''amor'', but ''haec'' is feminine, agreeing with ''patria'':
:{{lang|la|'''hic''' amor, '''haec''' patria est}} = this is my love, this my country<ref>Virgil, ''Aeneid'', 4.345.</ref>

There is no [[indefinite article]] or [[definite article]] (the, a, an). Sometimes the weak [[determiner]] ''{{lang|la|is, ea, id}}'' (English "that, this") can serve for the definite article:

:{{lang|la|Persuāsīt populō ut '''eā pecūniā''' classis aedificārētur}}<ref>Nepos, ''Themistocles'' 2.2.</ref>
:"He persuaded the people that a fleet should be built with the money (with that money)"

==Adverbs==
Adverbs modify verbs, adjectives and other adverbs by indicating time, place or manner. Latin adverbs are indeclinable and invariable. Like adjectives, adverbs have positive, comparative and superlative forms.

The positive form of an adverb can often be formed from an adjective by appending the suffix ''-ē'' (2nd declension adjectives) or ''-(t)er'' (3rd declension adjectives). Thus the adjective {{lang|la|clārus, -a, -um}}, which means "bright", can be contrasted to the adverb {{lang|la|clārē}}, which means "brightly". The adverbial ending {{lang|la|-(i)ter}} is used to form adverbs from 3rd declension adjectives, for example {{lang|la|celer}} "quick", {{lang|la|celeriter}} "quickly". Other endings such as ''-ō'', ''-e'', ''-tim'' are also found.

The comparative form of an adverb is the same as the neuter nominative singular form of a comparative adjective and usually ends in ''-ius''. Instead of the adjective {{lang|la|clārior}}, which means "brighter", the adverb is {{lang|la|clārius}}, which means "more brightly".

The superlative adverb has the same base as the superlative adjective and always ends in a long ''-ē''. Instead of the adjective {{lang|la|clārissimus}}, which mean "very bright" or "brightest", the adverb is {{lang|la|clārissimē}}, which means "very brightly" or "most brightly".

==Prepositions==
===Prepositions===
A prepositional phrase in Latin is made up of a [[preposition]] followed by a noun phrase in the accusative or ablative case. The preposition determines the case that is used, with some prepositions allowing different cases depending on the meaning. For example, Latin ''in'' takes the accusative case when it indicates motion (English "into") and the ablative case when it indicates position (English "on" or "inside"):
:{{lang|la|in urbem}} = "into the city" (accusative)
:{{lang|la|in urbe}} = "in the city" (ablative)

Most prepositions take one case only. For example, all those that mean "from", "by", or "with" take the ablative:
:{{lang|la|ex urbe}} = "out of the city"
:{{lang|la|ab urbe}} = "(away) from the city"
:{{lang|la|cum Caesare}} = "with Caesar"

Other prepositions take only the accusative:
:{{lang|la|extrā urbem}} = "outside the city"
:{{lang|la|ad urbem}} = "to/near the city"
:{{lang|la|per urbem}} = "through(out) the city"
:{{lang|la|circum urbem}} = "around the city"

===Postpositions===
In addition, there are a few postpositions. {{lang|la|tenus}} "as far as" usually follows an ablative, sometimes a genitive plural case:{{sfn|Lewis|Short|2020|loc=s.v. {{lang|la|tenus}}}}
:{{lang|la|Taurō tenus}} "as far as Taurus"
:{{lang|la|Cūmārum tenus}} "as far as Cumae"

{{lang|la|versus}} "towards" is usually combined with {{lang|la|ad}} or {{lang|la|in}}:
:{{lang|la|ad Alpēs versus}} "towards the Alps"

{{lang|la|causā}} "for the sake of" follows a genitive:
:{{lang|la|honōris causā}} "for the sake of (doing) honour"

The word {{lang|la|cum}} "with" is usually a preposition, but with the personal pronouns {{lang|la|mē, tē, sē, nōbīs, vōbīs}} "me, you sg., him/herself/themselves, us, you pl." it follows the pronoun and is joined to it in writing:
:{{lang|la|cum eō}} "with him"
:{{lang|la|mēcum}} "with me"

Both {{lang|la|quōcum}} and {{lang|la|cum quō}} "with whom" are found.

{{lang|la|ūnus}} (one) can also be used in the plural, with plural-only nouns, e.g. {{lang|la|ūna castra}} "one camp", {{lang|la|ūnae litterae}} "one letter". For larger numbers plural-only nouns use special numerals: {{lang|la|bīna castra}} "two camps", {{lang|la|trīna castra}} "three camps". (See [[Latin numerals]].)

The numbers {{lang|la|quattuor}} (four) through {{lang|la|decem}} (ten) are not declined:
:{{lang|la|quattuor}} (4)
:{{lang|la|quīnque}} (5)
:{{lang|la|sex}} (6)
:{{lang|la|septem}} (7)
:{{lang|la|octō}} (8)
:{{lang|la|novem}} (9)
:{{lang|la|decem}} (10)

The "tens" numbers are also not declined:
:{{lang|la|vīgintī}} (20)
:{{lang|la|trīgintā}} (30)
:{{lang|la|quadrāgintā}} (40)
:{{lang|la|quīnquāgintā}} (50)
:{{lang|la|sexāgintā}} (60)
:{{lang|la|septuāgintā}} (70)
:{{lang|la|octōgintā}} (80)
:{{lang|la|nōnāgintā}} (90)

The numbers 11 to 17 are formed by affixation of the corresponding digit to the base {{lang|la|-decim}}, hence {{lang|la|ūndecim, duodecim, tredecim, quattuordecim, quīndecim, sēdecim, septendecim}}. The numbers 18 and 19 are formed by subtracting 2 and 1, respectively, from 20: {{lang|la|duodēvīgintī}} and {{lang|la|ūndēvīgintī}}. For the numbers 21 to 27, the digits either follow or are added to 20 by the conjunction {{lang|la|et}}: {{lang|la|vīgintī ūnus}} or {{lang|la|ūnus et vīgintī, vīgintī duo}} or {{lang|la|duo et vīgintī}} etc. The numbers 28 and 29 are again formed by subtraction: {{lang|la|duodētrīgintā}} and {{lang|la|ūndētrīgintā}}. Each group of ten numerals through 100 follows the patterns of the 20s but 98 is {{lang|la|nōnāgintā octō}} and 99 is {{lang|la|nōnāgintā novem}} rather than *{{lang|la|duodēcentum}} and *{{lang|la|ūndēcentum}} respectively.

Compounds ending in 1 2 and 3 are the only ones to decline:
:I saw 20 blackbirds = {{lang|la|vīgintī merulās vīdī}}
:I saw 22 blackbirds = {{lang|la|vīgintī duās merulās vīdī}} (where {{lang|la|duās}} changes to agree with {{lang|la|merulās}})

The "hundreds" numbers are the following:
:{{lang|la|centum}} (indeclinable)
:{{lang|la|ducentī, -ae, -a}}  (200)
:{{lang|la|trecentī, -ae, -a}}  (300)
:{{lang|la|quadringentī, -ae, -a}}  (400)
:{{lang|la|quīngentī, -ae, -a}}  (500)
:{{lang|la|sēscentī, -ae, -a}}  (600)
:{{lang|la|septingentī, -ae, -a}}  (700)
:{{lang|la|octingentī, -ae, -a}}  (800)
:{{lang|la|nōngentī, -ae, -a}}  (900)

However, 1000 is {{lang|la|mille}}, an indeclinable adjective, but multiples such as {{lang|la|duo mīlia}} (2000) have {{lang|la|mīlia}} as a neuter plural substantive followed by a partitive genitive:
:I saw a thousand lions = {{lang|la|mīlle leōnēs vīdī}}
:I saw three thousand lions = {{lang|la|tria mīlia leōnum vīdī}}

Ordinal numbers are all adjectives with regular first- and second-declension endings. Most are built off of the stems of cardinal numbers (for example, {{lang|la|trīcēsimus, -a, -um}} (30th) from {{lang|la|trīgintā}} (30), {{lang|la|sēscentēsimus, -a, -um}} {{lang|la|nōnus, -a, -um}} (609th) for {{lang|la|sēscentī novem}} (609). However, "first" is {{lang|la|prīmus, -a, -um}}, and "second" is {{lang|la|secundus, -a, -um}} (literally "following" the first; {{lang|la|sequi}} means "to follow").

==Verbs==
===Persons of the verb===
Each tense has endings corresponding to three persons in the singular, known as '''1st person singular''' ("I"), '''2nd person singular''' ("you sg."), '''3rd person singular''' ("he, she, it"), and three in the plural, known as '''1st person plural''' ("we"), '''2nd person plural''' ("you pl."), and '''3rd person plural''' ("they"). Unlike Ancient Greek, there is no [[Dual (grammatical number)|dual]] number in the Latin verb.

{| class="wikitable"
|-
!1st sg.<br />2nd sg.<br />3rd sg.
|''I<br />you sg.<br />he, she, it''
|'''{{lang|la|amō<br />amās<br />amat|italic=no}}'''
|I love<br />you sg. love <br />he, she, it loves
|-

|'''{{lang|la|amāmus<br />amātis<br />amant|italic=no}}'''
|we love<br />you pl. love<br />they love
|-
|}

Unlike in Spanish, French, and other Romance languages, there are no respectful 2nd person forms in Latin grammar: the 2nd person singular is used even when addressing a person of high status. However, the 1st person plural is often used to mean "I".{{sfn|Allen|Greenough|Kittredge|Howard|1903|p=63}}

===Gender===
Most verbs do not show grammatical gender: the same ending is used whether the subject is "he", "she", or "it". However, when a verb is made periphrastically out of a participle and part of the verb {{lang|la|sum}} "I am", the participle shows gender, for example:
*{{lang|la|missus est}} "he was sent"
*{{lang|la|missa est}} "she was sent"

Impersonal verbs, such as {{lang|la|nūntiātum est}} "it was reported", are neuter singular.

===Voice===
Latin verbs have two voices, '''[[Active voice|active]]''' (e.g. {{lang|la|dūcō}} "I lead") and '''[[Passive voice|passive]]''' (e.g. {{lang|la|dūcor}} "I am led").

{| class="wikitable"
|-
!Active
|''(doing)''
|'''{{lang|la|dūcō|italic=no}}'''
|I lead, I am leading
|-
!Passive
|''(being done)''
|'''{{lang|la|dūcor|italic=no}}'''
|I am led, I am being led
|-
|}

In addition there are a few verbs (e.g. {{lang|la|sequor}} "I follow") which have the endings of passive verbs but with an active meaning, a relic of the older [[mediopassive]] voice. These verbs are known as '''[[deponent verb|deponent]]''' verbs.{{sfn|Kennedy|1962|p=59}}
[[Intransitive verb|Intransitive]] verbs such as {{lang|la|sum}} "I am" usually have no passive voice. However, some intransitive verbs can be used in the passive voice, but only when impersonal, e.g. {{lang|la|pugnātum est}} "(a battle) was fought", {{lang|la|ventum est}} "they came" (literally, "it was come").

===Mood===
Latin verbs have three [[Grammatical mood|moods]]: indicative, subjunctive, and imperative:{{sfn|Kennedy|1962|p=58}}

{| class="wikitable"
|-
!Indicative
|''(actual)''
|'''{{lang|la|dūcit|italic=no}}'''
|he leads, he is leading
|-
!Subjunctive
|''(potential)''
|'''{{lang|la|dūcat|italic=no}}'''
|he may/would/should lead
|-
!Imperative
|''(command)''
|'''{{lang|la|dūc!|italic=no}}'''
|lead!
|-
|}

Ordinary statements such as {{lang|la|dūcō}} "I lead" or {{lang|la|vēnit}} "he came" are said to be in the '''[[Realis mood|indicative]]''' mood. The '''[[Subjunctive mood|subjunctive]]''' mood (e.g. {{lang|la|dūcat}} "he may lead, he would lead" or {{lang|la|dūxisset}} "he would have led") is used for potential or hypothetical statements, wishes, and also in [[Latin indirect speech|reported speech]] and certain types of subordinate clause. The '''[[Imperative mood|imperative]]''' mood (e.g. {{lang|la|dūc}} "lead!") is a command.

In addition Latin verbs have a number of non-finite forms, such as the [[infinitive]] and various participles.

===Regular and irregular verbs===
{{Hatnote|Detailed information and conjugation tables can be found at [[Latin conjugation]].}}

Most Latin verbs are regular and follow one of the five patterns below.{{sfn|Kennedy|1962|pp=64-84}} These are referred to as the 1st, 2nd, 3rd, and 4th conjugation, according to whether the infinitive ends in {{lang|la|-āre, -ēre, -ere}} or {{lang|la|-īre}}.{{sfn|Kennedy|1962|p=60}} (Verbs like {{lang|la|capiō}} are regarded as variations of the 3rd conjugation, with some forms like those of the 4th conjugation.)

Other verbs like {{lang|la|sum}} "I am" are irregular and have their own pattern.{{sfn|Kennedy|1962|pp=62, 85–88}}

|-
|}

Compound verbs such as {{lang|la|adsum}} "I am present", {{lang|la|nōlō}} "I don't want", {{lang|la|redeō}} "I go back", etc., usually have the same endings as the simple verbs from which they are made.

===Tenses===
{{Main|Latin tenses}}

====A 3rd conjugation example====
Latin verbs have six basic [[grammatical tense|tenses]] in the indicative mood. Three of these are based on the present stem (e.g. ''dūc-'') and three on the perfect stem (e.g. ''dūx-'').

In addition, there are four tenses in the subjunctive mood, and two in the imperative.

Further tenses can be made periphrastically by combining participles with the verbs {{lang|la|sum}} "I am" or {{lang|la|habeō}} "I have", for example {{lang|la|ductūrus eram}} "I was going to lead" or {{lang|la|ductum habeō}} "I have led".

The following table gives the various forms of a 3rd conjugation verb {{lang|la|dūcō}}. As with other verbs, three different stems are needed to make the various tenses: {{lang|la|dūc-}} in the three non-perfect tenses, {{lang|la|dūx-}} in the three perfect tenses, and {{lang|la|duct-}} in the perfect participle and supine. The perfect and supine stems for any particular verb cannot always be predicted and usually have to be looked up in a dictionary.

A distinction between perfective [[grammatical aspect|aspect]] (''I did'') and imperfective aspect (''I was doing'') is found only in the past in Latin. In the present or future, the same tenses have both aspectual meanings.

Unlike in Ancient Greek or modern English, there is no distinction between perfect (''I have done'') and simple past (''I did''). The same tense, known in Latin grammar as the perfect tense, has both meanings.

The passive imperative is almost never used except in deponent verbs, e.g. {{lang|la|sequere mē!}} "follow me!"

====Variations====
The different conjugations differ in some tenses. For example, in the '''future tense''':
*1st and 2nd conjugation verbs and {{lang|la|eō}} have the endings {{lang|la|-bō, -bis, -bit, -bimus, -bitis, -bunt}} (e.g. {{lang|la|amābō}} "I will love", {{lang|la|vidēbō}} "I will see", {{lang|la|ībō}} "I will go"). 
*3rd and 4th conjugation verbs and {{lang|la|volō}} and {{lang|la|ferō}} have the endings {{lang|la|-am, -ēs, -et, -ēmus, -ētis, -ent}} ({{lang|la|dūcam}} "I will lead", {{lang|la|audiam}} "I will hear"). 
*{{lang|la|Sum}} and {{lang|la|possum}} have the endings {{lang|la|erō, eris, erit, erimus, eritis, erunt}} ({{lang|la|erō}} "I will be", {{lang|la|poterō}} "I will be able")

In the '''imperfect indicative''':
*Most verbs have the endings {{lang|la|-bam, -bās, -bat, -bāmus, -bātis, -bant}} (e.g. {{lang|la|amābam, vidēbam, dūcēbam, capiēbam, ferēbam, volēbam}})
*{{lang|la|Sum}} and {{lang|la|possum}} have {{lang|la|eram, erās, erat, erāmus, erātis, erant}} (e.g. {{lang|la|poteram}} "I was able")

They also differ in the '''present subjunctive''':
*1st conjugation verbs have the endings {{lang|la|-em, -ēs, -et, -ēmus, -ētis, -ent}} (e.g. {{lang|la|amem}} "I may love")
*2nd, 3rd, 4th conjugations have {{lang|la|-am, -ās, -at, -āmus, -ātis, -ant}} ({{lang|la|videam}} "I may see", {{lang|la|dūcam}} "I may lead", {{lang|la|audiam}} "I may hear", {{lang|la|eam}} "I may go")
*{{lang|la|Sum}}, {{lang|la|possum}}, {{lang|la|volō}} have {{lang|la|-im, -īs, -it, -īmus, -ītis, -int}} ({{lang|la|sim}} "I may be", {{lang|la|possim}} "I may be able", {{lang|la|velim}} "I may wish")

The '''imperfect subjunctive''' of every verb looks like the infinitive + an ending:
*Regular: {{lang|la|amārem, vidērem, dūcerem, caperem, audīrem}}
*Irregular: {{lang|la|essem, possem, ferrem, vellem, īrem}}

In the various '''perfect tenses''', all verbs have regular endings. However, the stem to which the perfect endings are added cannot always be guessed, and so is given in dictionaries.

==Word order==
{{Main|Latin word order}}
Latin allows a very flexible word order because of its inflectional syntax. Ordinary prose tended to follow the pattern of subject, direct object, indirect object, adverbial words or phrases, verb (with the proviso that when noun and verb make a compound, as {{lang|la|impetum facio}} "I attack / make an attack" the noun is generally placed close to the verb).{{sfn|Devine|Stephens|2006|p=79}} Any extra but subordinate verb, such as an infinitive, is placed before the main verb. Adjectives and participles usually directly follow nouns unless they are adjectives of beauty, size, quantity, goodness, or truth, in which case they usually precede the noun being modified. However, departures from these rules are frequent.

Relative clauses are commonly placed after the antecedent that the relative pronoun describes. Since grammatical function in a sentence is based not on word order but on inflection, the usual word order in Latin was often abandoned with no detriment to understanding but with various changes in emphasis.

While these patterns of word order were the most frequent in Classical Latin prose, they were frequently varied. The strongest surviving evidence suggests that the word order of ''colloquial'' Latin was mostly [[Subject-Object-Verb]]. That can be found in some very [[conservative (language)|conservative]] Romance languages, such as [[Sardinian language|Sardinian]] and [[Sicilian language|Sicilian]] in which the verb is still often placed at the end of the sentence (see [[Vulgar Latin]]). On the other hand, [[subject-verb-object]] word order was probably also common in ancient Latin conversation, as it is prominent in the [[Romance languages]], which evolved from Latin.{{sfn|Devine|Stephens|2006|pp=3-5|ps=&nbsp; "Word order is what gets the reader of Latin from disjoint sentences to coherent and incrementally interpretable text."}}

In [[poetry]], however, word order was often changed for the sake of the meter for which vowel quantity (short vowels vs. long vowels and diphthongs) and consonant clusters, not rhyme and word stress, governed the patterns. One must bear in mind that poets in the Roman world wrote primarily for the ear, not the eye; many premiered their work in recitation for an audience. Hence, variations in word order served a rhetorical as well as a metrical purpose; they certainly did not prevent understanding.

In [[Virgil]]'s ''[[Eclogues]]'', for example, he writes, {{lang|la|Omnia vincit amor, et nōs cēdāmus amōrī!}}: "''Love'' conquers ''all'', let us too yield to ''love!''". The words {{lang|la|omnia}} (all), ''amor'' (love) and {{lang|la|amōrī}} (to love) are thrown into relief by their unusual position in their respective phrases.

The ending of the common Roman name ''Mārcus'' is different in each of the following pairs of examples because of its grammatical usage in each pair. The ordering in the second sentence of each pair would be correct in Latin and clearly understood, whereas in English it is awkward, at best, and meaningless, at worst:

:{{lang|la|Mārc'''us''' ferit Cornēliam}}: Marcus hits Cornelia. (subject–verb–object)
:{{lang|la|Mārc'''us''' Cornēliam ferit}}: Marcus Cornelia hits. (subject–object–verb)
:{{lang|la|Cornēlia dedit Mārc'''ō''' dōnum}}: Cornelia gave Marcus a gift. (subject–verb–indirect object–direct object)
:{{lang|la|Cornēlia Mārc'''ō''' dōnum dedit}}: Cornelia (to) Marcus a gift gave. (subject–indirect object–direct object–verb)
