Etymologically, the entry records: Late Middle English cavernous, cavernose, borrowing from Old French caverneux or Latin cavernōsus (“full of hollows or cavities”), from caverna (“a hollow, cavity, cave”) + -ōsus (“-ous, -ose”, adjectival suffix); equivalent to cavern + -ous. 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 cavernous, spelled C-A-V-E-R-N-O-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
