Rus. neprijatel' (distinct from vrag). Rus. vrag (O.C.S. vragu) is cognate with Lith. vargas "misery" (see
urge), and probably is related to P.Gmc. *wargoz, source of O.N. vargr "outlaw," hence "wolf;" Icel. vargur "fox," O.E. wearg "criminal, felon;" which likely were the inspirations for J.R.R. Tolkien's warg "a kind of large ferocious wolf" in "The Hobbit" (1937) and "Lord of the Rings." Related: Enemies.
