Etymologically, the entry records: From Middle English Thursday, Thuresday, from Old English þursdæġ, þuresdæġ (“Thursday”), possibly from a contraction of þunresdæġ (“Thursday”, literally “Thor's day”), but more likely of North Germanic origin, from Old Norse þórsdagr; all from Proto-West G… 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 Thursday, spelled T-H-U-R-S-D-A-Y, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
