Etymologically, the entry records: From Middle English sheth, shethe (“holder for a sword, knife, etc., scabbard, sheath”) [and other forms], from Old English sċēaþ (“sheath”), from Proto-West Germanic *skaiþiju, from Proto-Germanic *skaiþiz (“sheath; covering”), from Proto-Indo-European *sk… 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 sheath, spelled S-H-E-A-T-H, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
