1335, from Anglo-Fr.
erraunt, from two O.Fr. words that were confused even before they reached Eng.: 1. O.Fr.
errant, prp. of
errer "to travel or wander," from L.L.
iterare, from L.
iter "journey, way," from root of
ire "to go" (see
ion); 2. O.Fr.
errant, pp. of
errer (see
err). Much of the sense of the latter has gone with Eng.
arrant (q.v.).
