Editing Latin declension (section)

=== Personal pronouns ===
The first and second persons are irregular, and both pronouns are indeclinable for gender; and the third person reflexive pronoun sē, suī always refers back to the subject, regardless of whether the subject is singular or plural.

The genitive forms {{wikt-lang|la|meī}}, {{wikt-lang|la|tuī}}, {{wikt-lang|la|nostrī}}, {{wikt-lang|la|vestrī}}, {{wikt-lang|la|suī}} are used as complements in certain grammatical constructions, whereas {{wikt-lang|la|nostrum}}, {{wikt-lang|la|vestrum}} are used with a [[partitive]] meaning ('[one] of us', '[one] of you'). To express possession, the possessive pronouns (essentially adjectives) {{wikt-lang|la|meus}}, {{wikt-lang|la|tuus}}, {{wikt-lang|la|noster}}, {{wikt-lang|la|vester}} are used, declined in the first and second declensions to agree in number and case with the thing possessed, e.g. {{lang|la|pater meus}} 'my father', {{lang|la|māter mea}} 'my mother'. The vocative singular masculine of {{lang|la|meus}} is {{lang|la|mī}}: {{lang|la|mī Attice}} 'my dear Atticus'.<ref>[[Cicero]], ''[[Epistulae ad Atticum]]'' 6.1.20 etc.</ref>

The possessive adjective {{lang|la|vester}} has an archaic variant, {{lang|la|voster}}; similar to {{lang|la|noster}}. Vocative of {{lang|la|meus}} is usually {{lang|la|mī}}, and rarely {{lang|la|meus}} also, like the nominative.

Usually, to show the ablative of accompaniment, {{wikt-lang|la|cum}} would be added to the ablative form. However, with personal pronouns (first and second person), the reflexive and the interrogative, ''-cum'' is added onto the end of the ablative form. That is: {{wikt-lang|la|mēcum}} 'with me', {{wikt-lang|la|nōbīscum}} 'with us', {{wikt-lang|la|tēcum}} 'with you', {{wikt-lang|la|vōbīscum}}, {{wikt-lang|la|sēcum}} and {{wikt-lang|la|quōcum}} (sometimes {{wikt-lang|la|quīcum}}).

Pronouns have also an emphatic form bi using the suffix ''-met'' ({{wikt-lang|la|egomet}}, {{wikt-lang|la|tūte}}/{{wikt-lang|la|tūtemet}}, {{wikt-lang|la|nosmet}}, {{wikt-lang|la|vosmet}}), used in all cases, except by the genitive plural forms.

In accusative case, the forms ''mēmē'' and ''tētē'' exist as emphatic, but they are not widely used.

{{wikt-lang|la|se|Sē, suī}} has a possessive adjective: {{wikt-lang|la|suus|suus, sua, suum}}, meaning 'his/her/its/their own':

:{{lang|la|Patrem '''suum''' numquam vīderat.}} ([[Cicero]])<ref>[[Cicero]], ''[[Pro Rabirio Postumo]]'' 4</ref>
:"He had never seen '''his''' [own] father."

When 'his' or 'her' refers to someone else, not the subject, the genitive pronoun {{lang|la|eius}} (as well as ''eōrum'' and ''eārum'') 'of him' is used instead of ''suus'':
:{{lang|la|Fit obviam Clodiō ante fundum '''eius'''.}} ([[Cicero]])<ref>[[Cicero]], ''[[Pro Milone]]'' 29</ref>
:"He met Clodius in front of '''the latter's''' farm."

Despite its resemblance to the possessive adjectives {{lang|la|meus, tuus}} and {{lang|la|suus}}, {{lang|la|eius}} does not decline in agreement with the noun it refers to, in the way that an adjective would. For instance, "his father" in the accusative is {{lang|la|patrem eius}} (literally, "father of him"), not {{lang|la|patrem}} ''*eium'', in contrast with the reflexive formation {{lang|la|patrem suum}} ("his [own] father").

When one sentence is embedded inside another with a different subject, ''sē'' and ''suus'' can refer to either subject:
:{{lang|la|Patrēs conscrīptī ... lēgātōs in Bīthȳniam miserunt quī ab rēge peterent, nē inimīcissimum '''suum''' '''secum''' haberet '''sibi'''que dēderet.}} ([[Cornelius Nepos|Nepos]])<ref>[[Cornelius Nepos]], ''Hannibal'' 12.2</ref>
:"The senators ... sent ambassadors to Bithynia, who were to ask the king not to keep '''their''' greatest enemy '''with him''' but hand him over '''to them'''."

For the third-person pronoun {{wikt-lang|la|is}} 'he', see below.
