Etymologically, the entry records: PIE word *tréyes From Latin triad-, stem of trias (“three, triad”), from Ancient Greek τριάς (triás). By surface analysis, tri- + -ad. Sense 3 (“branch of a Chinese underground criminal society”) is due to the word being applied by the British authorities … 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 triad, spelled T-R-I-A-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
