Izzy

Izzy is an English pet form and diminutive that functions as a given name in its own right, derived from longer Hebrew-origin names whose root meaning is God will strengthen or God is my salvation, most commonly Isabel, Isabella, Isidore, or Israel. Its warm, informal sound made it popular as a nickname in Jewish immigrant communities of the early twentieth century, particularly for bearers of the name Israel or Isidore. It has grown increasingly common as an independent given name for both boys and girls in English-speaking countries. Related forms include Iz, Izzie, Isabel, Isabella, and Isadora.
