Etymology

Origin of peacock

First recorded in 1250–1300; Middle English pecok, pocok equivalent to pe- ( Old English pēa “peafowl,” from Latin pāvōn-, stem of pavō peacock ( def. ) ) + cok ( Old English coc cock 1 )

Explanation

A peacock is a shiny blue bird who fans out his large colorful iridescent tail feathers, especially when he’s flirting with the peahens. A peacock is a male peafowl. A male peacock is more flamboyant than his female counterpart — he’s the one with those long brilliant tail feathers marked with eye-like designs. If a man (a human!) dresses overly flashy, he’s “peacocking.” The writer Flannery O’ Connor was famous for having peacocks strut around her farm in Georgia. Peacocks also have a loud call that sounds almost like a human cry. The word peacock has many etymological influences, and it may ultimately come from the Tamil tokei.
