Etymologically, the entry records: Borrowed from New Latin vacuum (“vacuum”), a subsense of Classical Latin vacuum (“empty space”), a substantivised form of vacuus (“empty”); related to vacāre (“to be empty”). The exercise sense comes from analogy to the sucking action of a vacuum cleaner. 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 vacuum, spelled V-A-C-U-U-M, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
