Where the name Jack comes from

Jack is a medieval English pet form of John, from the earlier Jankin and Jackin.

John in turn travelled through Latin and Greek out of the Hebrew Yohanan, a name that praises divine grace. In time Jack became a common word for an ordinary man, and it appears in fairy tales and in folk heroes such as Jack the Giant Killer. A link with the French Jacques is sometimes proposed as well.
