Pronunciation

Etymology

It is borrowed from Latin pēnis (“tail; penis”), earlier *pesnis,[2][3][4] perhaps through French pénis,[2] from Proto-Indo-European *pes-, usually said to have meant penis originally,[3][2] source also of Greek πέος (péos), Sanskrit पसस् (pásas) and probably Old English fæsl, offspring.[3][5] De Vaan argues from Latin pēnītus, having a tail, that tail was the original Latin meaning.[3]

Earliest recorded meaning
