early 14c., "almighty, possessing infinite power," from Old French omnipotent "almighty, all-powerful" (11c.) and directly from Latin omnipotentem (nominative omnipotens) "all-powerful, almighty," from omnis "all" (see omni-) + potens (genitive potentis) "powerful" (see potent). Originally of God or a deity; general sense of "having absolute power or authority" is attested from 1590s. Related: Omnipotently.
