Etymologically, the entry records: From Middle English, borrowed from Old French longitude, from Latin longitūdō (“length, a measured length”), from longus (“long”). 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 longitude, spelled L-O-N-G-I-T-U-D-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
