prefix meaning "of man, pertaining to man," from comb. form of Gk. anthropos "man, human being" from Attic andra (gen. andros), from Gk. aner "man," from PIE *hner "man" (cf. Skt. nar-, Armenian ayr, Welsh ner). Anthropos sometimes is explained as a compound of aner and ops (gen. opos) "eye, face;" so lit. "he who has the face of a man."
