Etymologically, the entry records: From Middle English oblivious, from Latin oblīviōsus (“forgetful, oblivious”), formed from oblīvium (“forgetfulness, oblivion”) + -ōsus (“full of, overly, prone to”), from oblīvīscor (“to forget”). 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 oblivious, spelled O-B-L-I-V-I-O-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
