Pronunciation

  • IPA: /fis/[1]
  • IPA (Quebec): /fɪs/[1]
  • IPA (archaic): /fi/[1]

Forms

fils m (invariable)[1] Old French subject case fils, fiz, object case fil, Picard fieu.[2][3][4] The s is pronounced (/fis/); the older pronunciation /fi/ lasted until the 19th century.[5][1]

Etymology

It is inherited from Old French fils, inherited from Latin fīlius (“son, child”).[6][2][4][7][1] The modern form is the Old French subject case, kept because it was often used as a vocative, and probably also to avoid confusion with fil “thread”.[6][4]

Latin “fīlius”, like fēcundus, goes back to an Indo-European root “*dhē-” “to suck”; it first meant “nursling” and replaced the old Indo-European word for “son”.[2][8][3] Cognate with Romanian fiu, Italian figlio, Occitan filh, Catalan fill, Spanish hijo and Portuguese filho.[8][9]

Earliest recorded meaning

It is first found in the second half of the 10th century in the Vie de saint Léger, for a male child considered in relation to his parents; the Passion of Clermont (late 10th century) has fils Deu, the Son of God.[6][2]

Semantic evolution

In the early 12th century it also meant descendants, as in li fil des humes “the sons of men” (Oxford Psalter).[6][2] From about 1196 it was used for any boy, without displacing garçon; it survives as a form of address (mon fils !), especially in the south of France.[2][10]

Fils de famille dates from 1606, fils à papa is more recent.[2] The old pronunciation /fi/ gave insults such as fi de garce.[2] The diminutive fiston dates from 1585, beau-fils from 1468 and petit-fils from the 13th century.[2]
