Prōnōmina

Latin pronouns fall into eight classes by function:

(1) Personal (prōnōmen persōnāle) — ego "I", tū "you (sg.)", nōs "we", vōs "you (pl.)". No 3rd-person personal pronoun in Latin — its function is supplied by is, ea, id (a demonstrative).

(2) Reflexive (prōnōmen reflexīvum) — suī: refers back to the subject of the clause. No nominative; same forms for sg. and pl. The 1st and 2nd person reflexive use the personal pronouns themselves (mē, tē, nōs, vōs) since context disambiguates.

(3) Possessive (prōnōmen possessīvum) — meus, tuus, suus (reflexive), noster, vester. Adjectives in form, declining like bonus or pulcher.

(4) Demonstrative (prōnōmen dēmōnstrātīvum) — hic "this (near me)", iste "that (near you)", ille "that (yonder)", is "this/that, he/she/it" (anaphoric), īdem "the same".

(5) Intensive (prōnōmen intēnsīvum) — ipse "self": adds emphasis to a noun or pronoun. NOT reflexive (that's suī); it stresses identity.

(6) Interrogative (prōnōmen interrogātīvum) — quis, quid (substantive: "who?, what?"); quī, quae, quod (adjectival: "which?").

(7) Relative (prōnōmen relātīvum) — quī, quae, quod: introduces relative clauses. Same form as adjectival interrogative but in different syntactic position.

(8) Indefinite (prōnōmen indēfīnītum) — aliquis, quīdam, quisquam, nēmō, nūllus, nōnnūllus, quisque, quīvīs, quīlibet: refer to unspecified persons or things.

Several pronouns share the same root qu- (interrogative, relative, indefinite); their distinct functions are clarified by syntactic position and accompanying particles (-dam, -piam, -quam, -libet, -vīs).

The personal pronouns are normally omitted as subjects since the verb-ending makes them explicit; they appear only for emphasis or contrast: ego veniō "I (myself) come"; tū vērō "you, however".

The genitive forms are not used as possessives: instead, the possessive adjectives meus, tuus, noster, vester are used. The genitive is used only for objective uses: meī memor "mindful of me"; amor patriae "love for the country" (though this uses patria's gen., not pronoun's).

The two genitive forms in 1st/2nd plural have different functions:
• nostrī, vestrī: objective genitive ("of us, of you" — directed at us/you).
• nostrum, vestrum: partitive genitive ("of us, among us / of you, among you").
So memoria nostrī "memory of us" but quis nostrum? "who of us?".

The reflexive suī has no nominative and no distinction between singular and plural. It always refers back to the subject of its clause: sē laudat "he praises himself"; sē laudant "they praise themselves". Distinguish from non-reflexive eum, eam, id (= "him, her, it" — different person from subject).

The forms mēcum, tēcum, sēcum, nōbīscum, vōbīscum are written as one word, the preposition cum appended to the pronoun. This is unique to cum and to personal pronouns; with other prepositions, normal spacing applies (ad mē, ab eō).

Possessive pronouns are adjectives in form, agreeing with the thing possessed in gender, number, and case:

• meus, mea, meum "my".
• tuus, tua, tuum "your (sg.)".
• suus, sua, suum "his/her/its/their (own — reflexive)".
• noster, nostra, nostrum "our".
• vester, vestra, vestrum "your (pl.)".

All decline like 1·2-decl. adjectives. noster, vester follow the pulcher pattern (e dropped). meus has the irregular vocative mī (vocative singular masculine): mī fīlī "my son!".

The agreement is with the possessed item, NOT the possessor: meus liber "my book" (m.sg., agreeing with liber); mea casa "my house" (f.sg., agreeing with casa).

suus is reflexive: it always refers to the subject of its clause. To express "his" (someone else's), Latin uses the genitive of the demonstrative is — namely eius:

• Caesar suōs mīlitēs amat = "Caesar loves his (own = Caesar's) soldiers". Suōs reflexive.
• Caesar eius mīlitēs amat = "Caesar loves his (someone else's) soldiers". Eius not reflexive.

This rigorous distinction is one of Latin's most precise grammatical features.

Latin has four primary demonstratives, expressing different deictic distances from the speaker, plus an "identity" demonstrative īdem:

hic, haec, hoc "this (near me)" — 1st-person deixis. Proximal. Used for things present, near the speaker, or just mentioned.

iste, ista, istud "that (near you)" — 2nd-person deixis. Often (but not always) with disparaging tone in Cicero: "that (one of yours)". Refers to things near the addressee.

ille, illa, illud "that (yonder)" — 3rd-person, distal deixis. Refers to things far from both speakers, or to famous/well-known persons. Sometimes laudatory ("the famous"): ille Cicerō "the famous Cicero".

is, ea, id "this/that, he/she/it" — anaphoric, weakly demonstrative. Refers back to something already mentioned. Supplies the missing 3rd-person pronoun in Latin: is dīxit "he said". Weakest of all demonstratives — almost a colorless pronoun.

īdem, eadem, idem "the same" — formed from is + -dem. The -dem is invariable; is, ea, id declines normally before it.

All five demonstratives share the UNUS NAUTA pattern: genitive singular in -īus, dative singular in -ī (regardless of gender). This is one of Latin's most pervasive morphological patterns, shared with the nine "irregular" 1·2-decl. adjectives (Lectiō X § 112).

ipse, ipsa, ipsum "self, very" — used to emphasize a noun or pronoun, NOT to express reflexivity. The contrast is essential:

• Caesar sē laudat = "Caesar praises himself" (reflexive: subject = object).
• Caesar ipse mē laudat = "Caesar himself praises me" (intensive: emphasizes that it's Caesar, not someone else).
• Caesar sē ipse laudat = "Caesar himself praises himself" (both: ipse stresses, sē reflects).

Common uses:
• ipse cōnsul "the consul himself".
• ego ipse "I myself".
• vōs ipsī "you yourselves".
• verbum ipsum "the very word".
• ipse rēx "the king in person".

The declension follows the UNUS NAUTA pattern with a special twist: like ille but with -um in nom./acc. neuter sg. (ipsum, NOT *ipsud). Otherwise identical to ille in pattern.

Ipse can also intensify a meaning: ipsum tempus "the very moment"; ad ipsam mortem "to the very point of death". This intensifying use makes ipse a versatile particle for stressing any element in a sentence.

Latin has two distinct (but partially overlapping) qu- words:

quis, quid — substantive interrogative: "who?", "what?". Used alone, asking about identity. quis hoc dīxit? "Who said this?".

quī, quae, quod — adjectival interrogative ("which?") + relative ("who, which"). Used with a noun (interrogative) or after an antecedent (relative). quī mīles hoc fēcit? "Which soldier did this?"; mīles, quī hoc fēcit, vēnit "The soldier who did this came".

The two forms share most plural forms; they differ chiefly in the singular nominative (quis vs. quī) and accusative neuter (quid vs. quod).

Function distinctions:

(a) Substantive interrogative: stands alone, asks identity. quis vēnit? "Who came?"; quid vidēs? "What do you see?".

(b) Adjectival interrogative: with a noun, asks "which?". quī mīles? "Which soldier?"; quod opus? "Which work?".

(c) Relative: refers back to an antecedent, introduces a relative clause. vir quem amō "the man whom I love"; opus quod fēcī "the work that I did".

Tense and case in relative clauses follow strict rules: gender/number from antecedent, case from function within the relative clause.

Indefinite pronouns are formed from the qu- root with various particles, each conveying a distinct semantic shade:

(a) Generic indefinite — aliquis, aliquid "someone, something" (positive, generic). Plural aliquī. aliquis dīcit "someone says (or other)".

(b) Specific but unnamed — quīdam, quaedam, quoddam "a certain one/thing" (specific, but the speaker doesn't reveal). quīdam vir "a certain man".

(c) Universal denial / "any whatever" — quisquam, quidquam (or quicquam) "anyone, anything" (mostly in negative or quasi-negative contexts). nōn vēnit quisquam "no one came".

(d) Distributive "each" — quisque, quaeque, quidque "each one" — every individual, taken severally. suum cuique "to each his own".

(e) Free choice "any" — quīvīs, quaevīs, quodvīs and quīlibet "any you wish, any whatever". quīvīs cīvis "any citizen at all".

Negative indefinite:
• nēmō "no one" (sg. only; supplied in plural by nūllī). Genitive nūllīus from nūllus; ablative nūllō; otherwise nēminem, nēminī.
• nihil "nothing" (indecl.).
• nūllus, -a, -um "no, none" — declines like ūnus.
• nōnnūllus "some, several" (= nōn nūllus "not none"); nōnnēmō "some person".

Reciprocals are expressed by repetition or by alter...alter ("the one ... the other") and alius...alius ("one ... another"):
• amant inter sē "they love one another" (using inter+reflexive).
• alter alterum amat "each loves the other".
• aliī aliīs nocent "some harm others".

Pronominal adjectives — adjectives that decline like pronouns (UNUS NAUTA pattern, gen. -īus, dat. -ī): all five demonstratives plus ipse and the nine UNUS NAUTA adjectives (Lectiō X § 112: ūnus, sōlus, tōtus, ūllus, nūllus, alius, alter, uter, neuter).
