Etymologically, the entry records: From sea + cucumber, named in reference to its appearance. The term first appeared in common use in the 19th century, and is a calque of French concombre de mer according to the Oxford English Dictionary. 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 sea cucumber, spelled S-E-A- -C-U-C-U-M-B-E-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
