Pronunciation

Forms

cogner[1] Old French coignier, coigner;[2] Middle French also congner.[2]

Etymology

According to the TLFi it is formed from French coin (“wedge”) + -er, rather than taken from an Imperial Latin verb, Latin cuneō (“to wedge, fasten with a wedge”).[3] Rey leaves both possibilities open,[4] while the Grand Robert, the GLLF and the Petit Robert derive it from the Latin verb, itself from cuneus (“wedge”).[5][6][7] The FEW places it under the Latin noun.[8] Littré compared Berry cougner and Walloon counii.[2]

Earliest recorded meaning

The TLFi first finds it at the end of the 12th century in Jean le Nevelon's Vengeance Alexandre in the sense “to wedge in, jam”, and in the sense “to strike” in the first half of the 13th century.[3] The GLLF dates both senses from about 1131, in the Couronnement de Louis, where knights coignent their shields together.[6][2]

Semantic evolution

The old senses “to wedge in” and “to strike coins” went out of use;[4] “to drive in by striking” (13th century) survives transitively only in se cogner la tête contre les murs and, colloquially, in cogner quelqu'un “to beat someone up”.[4] The verb is more alive with contre or sur or used absolutely.[4] Littré still records the old sense “to drive into a corner” in the 16th century.[2]

In slang it has meant “to stink” since 1913, through the image of a blow to the nose; the reflexive se cogner quelque chose, “to do without it” in 1900, means “to treat oneself to it” from 1914, and in boxing the verb has meant “to beat” since 1926.[4] In Canada cogner des clous is to nod off sitting up.[3] Its derivatives are mostly slang: un cogne “policeman” (1800) and cogneur “boxer” (1920).[4][9]
