FromMiddle Frenchchasque, a backformation fromchascun, fromOld Frenchchascun (whence modernchacun). The Old French derives from a conflation ofVulgar Latin*quiscunus (fromquisqueunus) with synonymous*catunus (fromcataunus, fromAncient Greekκατά(katá), whenceCatalan,Spanish, andPortuguesecada). The short vowel (and hence the lack of a circumflex) is due to the usually unstressed position (cf.notre vs.lenôtre).
chaque (invariable)
Cognate toMiddle Frenchchasque(“each”), a back-formation fromOld Frenchchascun(“each one, every one”).
chaque m orf (invariable,masculine and feminine pluralchaques)
