1530s, from Medieval Latin vicegerentem (nominative vicegerens), from Latin vicem, accusative of vicus "stead, place, office," (see vicarious) + gerens, present participle of gerere "to carry" (see gest). From 1570s as an adjective.

late 15c., "living creature killed and offered as a sacrifice to a deity or supernatural power, or in the performance of a religious rite;" from Latin victima "sacrificial animal; person or animal killed as a sacrifice," a word of uncertain origin. Perhaps related to vicis "turn, occasion" (as in vicarious), if the notion is an "exchange" with the gods. Perhaps distantly connected to Old English wig "idol," Gothic weihs "holy," German weihen "consecrate" (compare Weihnachten "Christmas") on notion of "a consecrated animal."

Weaker sense of "person taken advantage of, one who is cheated or duped" is recorded from 1781.
