défense f (plural défenses)[1]

Etymology

It is borrowed from Late Latin dēfēnsa (“defence”), the feminine past participle, used as a noun, of Latin dēfendō (“to ward off, defend”), the source of défendre.[2][3][4][5][6] The Late Latin word was created in place of classical dēfēnsiō.[5] Old texts also have defension and defendement.[7]

Compare Old Occitan defensa and Spanish defensa.[7]

Earliest recorded meaning

The Lois de Guillaume le Conquérant (mid-12th century) have defense de plait, “defending oneself in a lawsuit”.[2][3][7]

Semantic evolution

In law it also meant the means used to defend one's cause (1249), and in 1851 (Cournot) the accused and his counsel, as opposed to the prosecution.[2][3] Chrétien de Troyes uses it for resisting a feeling (1176), for defence in combat (1177–1178) and for the means of defence, the battlements of a tower (1176).[2][3] The military sense now makes it almost a euphemism for war, as in ministère de la Défense.[3]

After another sense of the verb it has meant a prohibition since 1177 (Chrétien's Chevalier au lion); the sense “objection” (1165–1170) has died out.[2][3] From the 15th century it was a fortification term for stakes, and the long projecting tooth of some mammals, the elephant's tusk, is in Ambroise Paré (1585).[5][3][4] défenseur dates from 1213, and défensif from the 14th century.[5]
