What's the difference between i.e. and e.g.?
early 14c., from Old French omnipotent "almighty, all-powerful" (11c.) or directly from Latin omnipotentem (nominative omnipotens) "all-powerful, almighty," from omnis "all" (see omni-) + potens (genitive potentis) "powerful" (see potent). Strictly only of God or a deity; general sense of "having absolute power or authority" is attested from 1590s.
