Etymologically, the entry records: Collectively borrowed from Early Modern Spanish zero, Middle French zero, and (their etymon) Old Italian zero, from Medieval Latin zēphirum, from Arabic صِفْر (ṣifr, “nothing; cipher”), itself calqued from Sanskrit शून्य (śūnyá, “void; nothingness”). Double… 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 zero, spelled Z-E-R-O, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
