Forms

moechus m (genitive moechī, feminine moecha); second declension[1] An inscription has the vocative moice;[2][3] moecus is also found.[2][3]

Etymology

It is borrowed from Ancient Greek μοιχός (moikhós, “adulterer”).[2][4][1] Köbler mentions, with a question mark, Pokorny's root Proto-Indo-European *meyǵʰ- (“to urinate”) for the Greek word.[5]

Earliest recorded meaning

Köbler dates it from Plautus, whose Miles Gloriosus calls a man a great womaniser.[5][4]

Semantic evolution

It is an adulterer or fornicator, in Terence, Horace and Juvenal.[4] A grammarian insists that the word for adulterer is spelled with ⟨oe⟩, but inscriptions have the vocative ⟨moice⟩ and the spellings ⟨moecus⟩ and ⟨moeccus⟩ occur;[2][3] Catullus has the feminine vocative ⟨moeca⟩.[2][3] Church Latin glosses it adulterer.[6]
