Etymologically, the entry records: From Middle English crabbe, from Old English crabba (“crab; crayfish; cancer”), from Proto-West Germanic *krabbō, from Proto-Germanic *krabbô, from *krabbōną (“to creep, crawl”), from Proto-Indo-European *grobʰeh₂yéti (“scratch, claw at”), a metathesised o-… 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 crab, spelled C-R-A-B, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
