Our Hunspell-derived misspelling index lists 6 documented wrong-spelling variants for torus, with forms such as "otrus", "torrus", and "torsu".

Etymologically, the entry records: Borrowed from Latin torus (“a round, swelling, elevation, protuberance”). 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 torus, spelled T-O-R-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
