Etymologically, the entry records: From a being region of space having H_(II) emission lines in its spectrum. 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 H II region, spelled H- -I-I- -R-E-G-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
