Etymologically, the entry records: PIE word *swé From rightly + so (“in a particular manner”). 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 rightly so, spelled R-I-G-H-T-L-Y- -S-O, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
