Forms

casquette f (plural casquettes)[1]

Etymology

It is formed from French casque + -ette, with the diminutive suffix.[2][3][1] The TLFi dates it to 1813,[2] the DHLF to 1817,[4] and Bloch and Wartburg and the GLLF to 1820.[5][6] Littré derived it from casquet instead,[7] a word the TLFi records from 1556 to 1704.[2]

The base is from Spanish casco (“potsherd, skull, helmet”), a deverbal noun of cascar (“to break”), from Vulgar Latin *quassicō, a derivative of Latin quassō, the source of casser.[2][5] From the beginning the cap was a soft headgear, and its sense has always stood apart from that of the helmet.[4]

Earliest recorded meaning

It is first found in 1813, in Jouy's L'Hermite de la Chaussée d'Antin, for a cap with a visor.[2][3]

Semantic evolution

The cap spread widely in the 1830s and became the mark of the working class and of certain military ranks.[4] The casquette à pont, with a raised crown, was adopted about 1900 by cattle dealers and then by hooligans.[8][9]

In 1844 Vidocq records casquette as an adjective meaning “drunk”, modelled on être coiffé “to be drunk”.[2] By metonymy the cap stands for the head in en avoir ras la casquette “to be fed up”, parallel to ras le bol,[4][9] and the familiar cry vas-y, allons-y casquette ! is recorded in 1911.[4] Since the cap can stand for an office, avoir plusieurs casquettes means to hold several important posts at once.[4][10][9]
