απάνθρωπος

Etymology: From Ancient Greek ἀπάνθρωπος (apánthrōpos), from ἀ- (a-) 'not, without' + ἄνθρωπος (ánthrōpos) 'human'. The prefix ἀ- negates the meaning of the root word, creating the sense of 'not human' or 'lacking human qualities'. The root ἄνθρωπος gives us English words like 'anthropology' (the study of humans) and 'misanthrope' (someone who dislikes humans).
