meum

Meum is the neuter singular form of the Latin possessive adjective meaning "my" or "mine." It is part of the possessive adjectives meus, mea, meum that modify nouns and agree with their gender, number, and case. In typical usage meum is used with neuter nouns in the nominative and accusative singular, as in opus meum "my work." For masculine nouns, use meus (e.g., liber meus "my book"); for feminine nouns, use mea (e.g., carta mea "my letter"). Like other possessive adjectives, meum is declined in parallel with the noun it modifies.

Meum may also be used as a substantive pronoun meaning "mine" in phrases where the noun is understood, e.g., meum est "it is mine." The form appears in Classical Latin literature and is sometimes used in legal or rhetorical Latin.

Etymology and usage: Meum derives from the Latin possessive adjective family and is a standard element of Latin grammar, attested from Classical times through Late Latin and into modern scholarly texts. It emphasizes possession in a gender- and case-aware way, mirroring the behavior of other adjectives in its class.
