Etymologically, the entry records: PIE word *tréyes From Middle English thirde, thridde, from Old English þridda, from Proto-Germanic *þridjô, from Pre-Germanic *tretyós, a remodeling of Proto-Indo-European *tr̥tyós. 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 third, spelled T-H-I-R-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
