Bill is a masculine given name, generally a short form (hypocorism) of William. It can also be used as the adaptation into English of the popular Greek name Vasilis or Vasileios (Basil), especially amongst Greek immigrants in English-speaking countries, probably due to similarity in the sound.^{[ citation needed ]}
