Etymologically, the entry records: The illusion was popularized in the English-speaking world by Edward B. Titchener in a 1901 psychology textbook. 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 Titchener circles, spelled T-I-T-C-H-E-N-E-R- -C-I-R-C-L-E-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
