Etymologically, the entry records: From taxonomic name Cactus, a name given in 1752 by Linnaeus for a genus of cacti (now superseded by the genus name Mammillaria), from Latin cactus, from Ancient Greek κάκτος (káktos, “cardoon”), possibly of Pre-Greek origin. 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 cactus, spelled C-A-C-T-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
