Forms

imaginaire (plural imaginaires)[1]

Etymology

It is borrowed from Latin imāginārius (“feigned, existing only in the imagination”), a word of the Imperial period,[2][3][4] derived from imāgō (“image”).[2][1][5] The Latin noun also gave image.[2][3] Cognate with Old Occitan imaginari, Spanish imaginario and Italian immaginario.[6]

Earliest recorded meaning

It is first found in 1496, in Jean de Vignay's Miroir historial, for what seems real but is only an appearance: a man sees in a dream comme par vision imaginaire a tree of marvellous size.[2][3]

Semantic evolution

Anglo-Norman already had ymaginaire, as a noun for a bearer of images (1271–1272) and as an adjective meaning “thinkable” (late 13th century).[7]

In the 17th century Descartes used it in mathematics, with racines imaginaires in his Géométrie (1637) and espaces imaginaires;[2][3][4] nombres imaginaires is recorded in 1902.[2][3][4] Pascal used it in 1658 of a person who is something only in his own imagination, the sense of Molière's Malade imaginaire (1673).[2][3][4]

As a noun, l'imaginaire has meant the realm of the imagination and its products since 1820 (Maine de Biran);[2][3] in psychoanalysis Lacan made it one of the registers of the psyche (1966), marked by the relation to the image of one's like.[3][8]
