Oz

Oz functions both as a Hebrew name and as an English short form. In Hebrew, oz means strength or power, making it an independent masculine given name in Israeli usage. In English-speaking contexts, Oz arose largely as a diminutive of Oswald, Osborn, or other Old English names beginning with the element os, meaning god, though it gained broader cultural recognition through L. Frank Baum's 1900 fantasy novel The Wonderful Wizard of Oz. Related forms include Ozzie and Ozzy.
