insanité f (plural insanités)[1]

Etymology

It is borrowed from English insanity (“madness”), recorded in English since the late 16th century.[2][3][4][5][6] The English word is either derived from insane or taken from Latin īnsānitās (“ill health, madness”),[2] itself from īnsānus (“mad”).[4][7] This Latin noun was less common than īnsānia, which gave the 16th-century French insanie “madness” (about 1510), a borrowing that has disappeared.[2][3]

Earliest recorded meaning

It is first found in 1784 in the Courrier de l'Europe, meaning the state of a diseased mind, madness.[2][5]

Semantic evolution

The word spread in the early 19th century, chiefly in the sense of a senseless word or act, une insanité, des insanités (1832).[3] Bescherelle records this use in 1845, with c'est une insanité.[2][5] It is more common than the adjective insane.[3]

Timeline
