Pronunciation

Forms

cornu (feminine cornue, masculine plural cornus, feminine plural cornues)[1]

Etymology

It is inherited from Latin cornūtus (“horned”), the adjective of cornū (“horn”).[2][3][4][1][5] In Late Latin the word also meant “specious”.[6]

Cognate with Italian cornuto, Romanian cornut, Old Occitan cornut, Catalan cornut, Spanish cornudo and Portuguese cornudo.[7][8]

Earliest recorded meaning

In the Roman de Thèbes (about 1150) it describes stones with jutting corners or two points, chaillos cornus; the sense “having horns” follows at the end of the 12th century.[2]

Semantic evolution

Like corne, the adjective was used of animals and of mythological beings such as devils and satyrs.[3][8] From 1608 it was applied to a deceived husband.[2][3] Between the 13th and the 16th century it could also mean “foolish”.[4]

In classical French it also meant “odd, extravagant”, by analogy with argument cornu “specious argument” (Cotgrave, 1611),[3][6] and lune cornue was the crescent moon.[3] The compound biscornu later took over the sense “bizarre” and pushed cornu out of it.[3]
