Etymologically, the entry records: From French bilieux, from Latin bīliōsus (“full of bile”), from bīlis (“bile”) + -ōsus (“full of”). 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 bilious, spelled B-I-L-I-O-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
