Pronunciation
- IPA: /kɔ̃.plɛks/[1]
Forms
complexe (plural complexes)[1]
Etymology
It is borrowed from Latin complexus (“made of interwoven elements”),[2][3][4][5] the past participle of complector (“to embrace, encompass”), from com- and plectō (“to plait, interweave”).[3][6]
The psychoanalytic sense is a calque of German Komplex, a term first used by the physiologist Josef Breuer (1895) and then by Jung and Freud (“Ödipuskomplex”, 1909–1910).[2][3]
Earliest recorded meaning
Its first use, in Jean Le Fèvre's La Vieille (14th century), is isolated and its sense unclear (Complexion est sans complexe).[2][3]
Semantic evolution
The adjective was taken up in the 16th century for what is made of different elements (complixe querelle, 1564),[2][3] and became a term of logic (vérité complexe, 1652, Bloch and Wartburg date it to 1667) and of mathematics (nombre complexe).[2][4][3] In everyday use it has drawn close to compliqué “complicated”.[3][7]
As a noun meaning “whole, aggregate” it is found in physiology in 1781, and Claudel used it for a group of industries in 1918.[2][3] The psychological sense is recorded in 1906,[8] and spread with Freudian psychoanalysis (complexe d'Œdipe);[3] complexe d'infériorité was in common use by 1930, and faire des complexes “to feel inferior” by 1960.[2][3] The noun complexité dates from 1755.[4]
