Pronunciation

  • Classical: [ˈme.ʊs][1]
  • Ecclesiastical: [ˈmɛː.us][1]

Forms

meus (feminine mea, neuter meum); first/second-declension determiner, with locative[1] The spelling mius appears in inscriptions, and the grammarian Velius Longus cites it as an archaism.[2] The masculine vocative is mī;[3] Virgil also uses meus as a vocative (sanguis meus).[3] Plautus has a genitive plural meūm for meōrum, and the emphatic forms meāpte and meōpte.[3]

Etymology

It is inherited from Proto-Italic *mejo- (“my”), a possessive adjective built on the oblique stem of the first-person pronoun (mē, see ego).[4][2][1] De Vaan takes ⟨*mejo-⟩ as a thematization of the old genitive ⟨*mei⟩, perhaps a remake of Proto-Indo-European *h₁moi (“of me”); the genitive ⟨meī⟩ that serves the personal pronoun is in fact the genitive of the possessive.[4]

The OLD compares the enclitic possessive Hittite -meš.[2]

Earliest recorded meaning

Its first record is the ablative plural meois on the Garigliano Bowl, an Old Latin inscription.[4] In literature it is found from Naevius on;[5] Plautus has appellat meō mē nōmine “he calls me by my name”.[2]

Semantic evolution

Meus means “my, mine” of anything possessed or used by the speaker, and emphatically “my own”; the neuter meum is “my property”, and meā rēfert or meā interest “it concerns me”.[2] Of persons it means “related to me, my friend or dependant”: it is added to the name of a friend or relative (Catō meus), the feminine mea is “my girl, my sweetheart”, the masculine plural meī “my family, my household”, and it is common in addresses (mī Aeschine).[2]

It also stands for a subjective or objective genitive (meā causā “for my sake”), and with the infinitive meum est means “it is my task” or “it is like me” (nōn est meum “it is not my way”).[2] In comedy meus est means “he is in my power”.[2]
