wiktionary
First attested in 1525. From Middle French perrot, either a diminutive of Pierre or a shortened form of perroquet (whence also parakeet). Compare French pierrot and Occitan parrat. A number of origins have been suggested for perroquet, such as Spanish periquito and Italian parrocchetto. The relationship between these various words is disputed. Replaced earlier popinjay.
