Forms

mon m (feminine ma, plural mes)[1] Old French mo (late 10th century), mun (about 1050), subject mes; feminine ma; plural mos, mas, then mes.[2][3]

Etymology

It is inherited from Old French mun, inherited from Late Latin mum, a reduced form (7th century) of meum (“my”), the accusative of the Latin possessive “meus” used unstressed.[3][4][5][1] The feminine “ma” continues “meam” contracted to “mam”, and the plural “mes” continues “meōs”, “meās” reduced to “mos”, “mas”.[3] The stressed form mien comes from “meum” in stressed position.[6] Wiktionary suggests that the form may also have been influenced by Gaulish mon (“my”).[1]

“Meus” derives from mē, the accusative of “ego”.[7]

Earliest recorded meaning

The Passion de Clermont (late 10th century) has mo as an object form: Vedez mo laz “see my side”.[2]

Semantic evolution

Elision before a vowel (m'espée “my sword”, 1080) was a feature of Old French, which survives in mamie (m'amie) and m'amour.[3][2] Mon before a feminine noun beginning with a vowel is found from the end of the 12th century (mon arme, about 1180, mon âme, before 1250) and became the rule.[3][2] Mon is used in addressing people (mon ami, mon père to a priest, 1657), and in the army before a rank (mon capitaine, 1873).[7][1]
