Etymologically, the entry records: From Japanese オタク (otaku, “anime obsessive, geek”) originally used in reference to the 1982 Macross fandom, from the honorific form お宅 (otaku, “you”), from the honorific form 宅 (taku, “home”) ("your home"). 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 otaku, spelled O-T-A-K-U, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
