Etymologically, the entry records: From Ancient Greek ἅλς (háls, “salt" or "sea”) + γεν- (gen-), "to produce" (coined by Berzelius in 1842). By surface analysis, halo- (“salt”) + -gen (“forming”). 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 halogen, spelled H-A-L-O-G-E-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
