Forms

insuffisant (feminine insuffisante, masculine plural insuffisants, feminine plural insuffisantes)[1] Middle French insufficiens (1323), modelled on the Latin.[2]

Etymology

It is formed from French in- + suffisant, after Late Latin insufficiens (“insufficient”) of Christian Latin,[2][3][4] which is made of in- and sufficiens (“sufficient”), the present participle of sufficiō (“to put under, suffice”).[5] The Latin word had already given the Middle French form insufficiens in a Bible translation of 1323.[2] The FEW files it under the Latin verb.[6]

Earliest recorded meaning

The TLFi first finds it in 1396 in the Coustumier de Dieppe, meaning “that does not suffice, that lacks the needed qualities”;[2] the Grand Robert, the Petit Robert and the DHLF give 1323, the date of the form insufficiens.[3][4][7]

Semantic evolution

Applied first to things that do not suffice,[2][7] it is used of people who lack the abilities required from 1476 (the DHLF) or 1474, in the Mystère de l'incarnation (the GLLF).[7][5] A sense “not showing enough regard”, about 1452, has been lost.[7] In medicine it is used as a noun with an adjective, for a person in whom a bodily function is impaired, as in insuffisant cardiaque.[4]
