Pronunciation

  • /de.fɛk.tif/[1]

Forms

défectif (feminine défective, masculine plural défectifs, feminine plural défectives)[1] Middle French also wrote it deffectif and defectif.[2][3]

Etymology

It is borrowed from Latin dēfectīvus (“imperfect, faulty”), a word of the Latin grammarians formed on dēfectum, the supine of dēficiō (“to be lacking, fail”).[4][5][6] The Latin adjective meant “imperfect, faulty” from about 400 (Augustine) and was used of words lacking some of their forms from the 4th century (Charisius).[3] The revised notice of the TLFi suggests that the word came into French either through writers such as Augustine and Gregory the Great and, for the grammatical sense, Donatus, or through the technical Medieval Latin of the schools.[3][7] Littré analyses the Latin verb as dē- and faciō (“to do, make”), properly “to undo”.[2]

The noun sense “mentally deficient person” is a calque of the English word defective, used in this sense from 1898.[3]

Cognate with Occitan defectiu, Spanish defectivo and Italian difettivo.[2]

Earliest recorded meaning

It is first found at the end of the 13th century in an Anglo-Norman legal text, the Mirror of Justices, in the sense “faulty, defective” of a thing: a point of the Great Charter is called defective par defaute de adicion de peine, “defective for want of an added penalty”.[3] The TLFi had dated the word from 1314, in Henri de Mondeville's Chirurgie, with the sense “having defects”.[4][5]

Semantic evolution

In Middle French the adjective meant “faulty” of things until the end of the 15th century and, from 1412–1413, “imperfect” of a person, in body or mind, until the mid-16th century.[3] This general sense then went out of use in favour of défectueux.[5]

The grammatical sense, of a verb or noun that lacks some of its forms, is recorded from the second half of the 14th century in a Latin–French glossary.[3] The older handbooks dated it much later: Bloch and Wartburg to 1629, the TLFi to Richelet's verbe défectif of 1680.[8][4][5] Littré also notes the word in geometry, for a kind of hyperbola.[2]

In the 20th century the word entered music, of a scale that does not use all seven notes of a mode (1925).[3] In 1935 the physician Alexis Carrel used it as a noun for a person lacking normal mental faculties, after the English usage; the sense was not taken up by medical writers or dictionaries.[3]
