Vicegerent
VICEGE'RENT, noun [Latin vicem gereus, acting in the place of another.]
A lieutenant; a vicar; an officer who is deputed by a superior or by proper authority to exercise the powers of another. Kings are sometimes called God's vicegerents. It is to be wished they would always deserve the appellation.
VICEGE'RENT, adjective Having or exercising delegated power; acting by substitution, or in the place of another.
