Our Hunspell-derived misspelling index lists 11 documented wrong-spelling variants for reactive, with forms such as "eractive", "raective", and "reacctive". Each variant represents a distinct typo pattern that appears often enough in corpora to be worth flagging, typically a doubled-consonant error, a silent-letter drop, or a vowel substitution.It also participates in 7 confusable-pair relationships, "receive", "relative", "realtime", and more, where similar look or sound leads writers to substitute one word for another in context.

Etymologically, the entry records: From react + -ive. 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 reactive, spelled R-E-A-C-T-I-V-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
