vice-president (n.)

also vice president, 1570s, "one who acts as a deputy for a president," from vice- + president. Made into an official rank and given a different meaning (vice = "next in rank to") in the U.S. Constitution (1787).

There seems to be no doubt of my election as V[ice] Pres[iden]t. It will have at least one advantage, that of permitting me to devote more of my time to my private affairs. [John C. Calhoun, letter to wife, Nov. 12, 1824]
