Word Origin & History
c.1400, n., "disciple of Aristotle," from O.Fr. perypatetique (14c.), from L. peripateticus "pertaining to the disciples or philosophy of Aristotle," from Gk. peripatetikos "given to walking about" (especially while teaching), from peripatein, from peri- "around" + patein "to walk." Aristotle's custom
was to teach while strolling through the Lyceum in Athens. In Eng., the philosophical meaning is older than that of "person who wanders about" (1617). As an adj., attested in Eng. 1566 in the philosophical sense, 1642 in the lit. sense.
