Etymology

It is inherited from Middle English advers, borrowed from Old French advers (earlier avers),[2][3][4] refashioned after Latin adversus (“turned against, facing; hostile”),[4][2] the past participle of advertō (“to turn toward”),[2][3] from ad (“to”) and vertō (“to turn”).[2][5] Compare averse.[5]

Earliest recorded meaning

Contrary, opposing: the late 14th century in Etymonline, about 1385 in Barnhart (Chaucer's Troilus and Criseyde);[2][3] the OED's first quotation, for unfavourable or hurtful, is from about 1374.[6]

Semantic evolution

Acting against, antagonistic is from about 1440,[6] and opposite in position from 1623.[6] The Old French word also meant unfriendly or foreign, as in gent avers, an infidel race.[2] A verb adverse, to oppose, was used from 1393.[6] The noun adversity is much older, from before 1200.[3]
