Etymologically, the entry records: From Middle English abak, from Old English onbæc, equivalent to a- (“towards”) + back. Compare West Frisian tebek (“aback”, adverb, literally “to/at back”), Swedish tillbaka (idem.). 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 aback, spelled A-B-A-C-K, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
