Etymologically, the entry records: Etymology tree Proto-Indo-European *bʰeg-der.? Proto-Germanic *baką Proto-West Germanic *bak Old English bæc Middle English bak English back From Middle English bak, from Old English bæc, from Proto-West Germanic *bak, from Proto-Germanic *baką, possibly fr… 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 back, spelled B-A-C-K, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
