Etymologically, the entry records: From New Latin differentiātus, perfect passive participle of differentiō (see -ate (verb-forming suffix) and -ate (noun-forming suffix)), from Latin differentia (“difference”); see difference. 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 differentiate, spelled D-I-F-F-E-R-E-N-T-I-A-T-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
