c.1300, from Anglo-Fr. conveier, from O.Fr. convoier "to escort," from V.L. *conviare "to accompany on the way," from L. com- "together" + via "way, road." It was a euphemism for "steal" 15c.-17c., which helped broaden its meaning. Related: Conveyed (c.1500); conveying (1590s); conveyer/conveyor (1510s).
