Etymologically, the entry records: Etymology tree Proto-Indo-European *h₃erg-der.? Proto-Indo-European *dʰeh₁-der.? Proto-Celtic *ordosder. Proto-Indo-European *weyk-der. Proto-Celtic *wiketider. Latin Ordovīcēslbor. English Ordovices Proto-Indo-European *-nós Proto-Italic *-nos Latin -nus L… 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 Ordovician, spelled O-R-D-O-V-I-C-I-A-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
