Anthropomorphic comes from the Late Latin word anthropomorphus, which itself traces to a Greek term birthed from the roots anthrōp- (meaning "human being") and -morphos (-morphous). Those ancient Greek roots have given form and personality to many English words. Anthrōp- relatives include anthropic ("relating to human beings or the period of their existence on earth"), anthropocentric ("interpreting or regarding the world in terms of human values and experiences"), anthropoid ("an ape"), and anthropology ("the study of human beings and their ancestors"). Derivatives of -morphos often end in -morphism, as in polymorphism ("the quality or state of existing in or assuming different forms"), or -morphic, as in biomorphic ("resembling the forms of living organisms").
