From Middle English po (“peacock") + coc (see cock (n.)). Po is from Old English pÄwa (“peafowl"), from Latin pavo (gen. pavonis), which, with Ancient Greek Ï„Î±ÏŽÏ‚ (taÅs), said to be ultimately from Tamil à®¤à¯‹à®•à¯ˆ (tÅkai) (but perhaps is imitative; Latin represented the peacock's sound as paupulo). Used as the type of a vainglorious person from late 14c. Its flesh superstitiously believed to be incorruptible (even St. Augustine credits this). "When he sees his feet, he screams wildly, thinking that they are not in keeping with the rest of his body."
