Etymologically, the entry records: Etymology tree Proto-Indo-European *bʰeh₂ǵosder.? Proto-Indo-European *bʰeh₂g-der.? Proto-Germanic *bōks Proto-West Germanic *bōk Old English bōc Middle English bok English book From Middle English bok, book, from Old English bōc, from Proto-West Germanic *… 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 book, spelled B-O-O-K, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
