Peep

Peep (pēp) , intransitive verb

[Of imitative origin; compare Old English pipen, French piper, pépier, Latin pipire, pipare, pipiare, Dutch & German piepen. Senses 2 and 3 perhaps come from a transfer of sense from the sound which chickens make upon the first breaking of the shell to the act accompanying it; or perhaps from the influence of peek, or peak. Compare Pipe.]
