Origin: 1635–45; < French envoyé envoy, noun use of past participle of envoyer to send < Vulgar Latin *inviāre, presumably orig. to be on a journey, verbal derivative of Latin in viā on one's way, en route
c.1660, from Fr. envoyé "messenger," lit. "one sent," n. use of pp. of envoyer "send," from V.L. *inviare "send on one's way," from L. in "on" + via "road." The same word was borrowed in M.E. to mean "a stanza of a poem sending it off to find readers" (late 14c.).
