Etymologically, the entry records: From Middle English either, from Old English ǣġhwæþer, from Proto-West Germanic *aiw + *gahwaþar. Akin to Old Saxon eogihwethar, iahwethar (Low German jeed); Old Dutch *iogewether, *iowether, *iother (Dutch ieder); Old High German eogihwedar, iegihweder, ie… 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 either, spelled E-I-T-H-E-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
