c. 1300, hauk, earlier havek (c. 1200), from Old English hafoc (West Saxon), heafuc (Mercian), heafoc, "hawk," from Proto-Germanic *habukaz (cognates: Old Norse haukr, Old Saxon habuc, Middle Dutch havik, Old High German habuh, German Habicht "hawk"), from a root meaning "to seize," from PIE *kap- "to grasp" (cognates: Russian kobec "a kind of falcon;" see capable). Transferred sense of "militarist" attested from 1956, probably based on its opposite, dove.
