Etymologically, the entry records: Etymology tree Latin dubiusbor. English dubious From Latin dubius; like doubt, from Latin duo (cognate to English two), implying “two alternatives” (yes or no, true or false, etc.). 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 dubious, spelled D-U-B-I-O-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
