Etymologically, the entry records: From French anaérobie, from Ancient Greek ἀν- (an-, “not”) + ἀήρ (aḗr, “air”) + βίος (bíos, “life”) + -ic. By surface analysis, an- + aerobic. 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 anaerobic, spelled A-N-A-E-R-O-B-I-C, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
