late 14c. (early 13c. as a surname), from Old French pigeon "young dove" (13c.), probably from Vulgar Latin *pibionem, dissimilation from Late Latin pipionem (nominative pipio) "squab, young chirping bird" (3c.), from pipire "to peep, chirp," of imitative origin. Meaning "one easily duped" is from 1590s. Replaced culver (Old English culufre, from Vulgar Latin *columbra, from Latin columbula) and native dove.
