Etymologically, the entry records: From Ancient Greek καταστροφή (katastrophḗ), from καταστρέφω (katastréphō, “I overturn”), from κατά (katá, “down, against”) + στρέφω (stréphō, “I turn”). 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 catastrophe, spelled C-A-T-A-S-T-R-O-P-H-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
