[C14: from Old Norse hreindӯri, from hreinn reindeer + dyr animal; related to Dutch rendier, German Rentier; see deer]
c.1400, from O.N. hreindyri "reindeer," from dyr "animal" (see deer) + hreinn, the usual name for the animal, from P.Gmc. *khrainaz (cf. O.E. hran "reindeer," Ger. Renn). Probably cognate with Gk. krios "ram," but folk-etymology associates it with rennen "to run."
