Etymologically, the entry records: From Middle English adversarie, from Anglo-Norman aversaire (in Wace's Life of Saint Margaret) and Old French aversier, aversaire (French adversaire), from Latin adversārius, from adversus (“turned toward”). Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is adversary, spelled A-D-V-E-R-S-A-R-Y, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
