assailant

Etymology

It is borrowed from Middle French assaillant (“attacking; attacker”),^{[2][3][4][5][6]} the adjective and noun use of the present participle of assaillir (“to assail”),^[2][4][6] which is from Old French asaillir,^[4] also assalir.^[3] The French word meant "attacking" from the late 12th century and "attacker" from the 13th.^[2] The Shorter Oxford analyses the English word as assail with the suffix -ant, after French.^[7] The Old French verb comes from Vulgar Latin *assaliō (“to leap at”),^[8][3] a variant of Latin assiliō (“to jump on”),^[8] formed from ad- (“to, toward”) and saliō (“to leap, jump”).^[8][3]

Earliest recorded meaning

A person who attacks someone: 1523, in Lord Berners's translation of Froissart's chronicles.^[2] Etymonline dates it to the 1530s and Dictionary.com to 1525–35;^[3][5] the native-formed assailer had been used in the same sense from about 1400.^[3][2]

Semantic evolution

Beside the physical attacker, the word soon meant a hostile critic or opponent in a controversy (1565).^[2] From 1586 to 1816 it also named the challenger in a joust, tournament or trial by combat, a sense the French word had carried since the 13th century.^[2] The adjective, "attacking", is recorded from 1592^[2] and is now archaic;^[4][7] Johnson (1755) gave both the adjective, quoting Milton's Samson Agonistes, and the noun, "he that attacks", in contrast to the defendant.^[9]
