Ozzie

Ozzie is a diminutive or nickname form of the name Oswald, which is of Old English origin. The name Oswald is derived from the elements 'os' meaning 'divine' and 'wald' meaning 'power' or 'ruler'.

The name Oswald was borne by several Anglo-Saxon kings and saints, including St. Oswald, who was a king of Northumbria in the 7th century. He was known for his efforts in spreading Christianity in England.

The nickname Ozzie likely emerged as a shortened and more casual form of Oswald, and it became particularly popular in the 20th century, perhaps influenced by the American baseball player and entertainer Ozzie Nelson.

While Ozzie is a diminutive, it has taken on a life of its own as a name, and is often given as a full name rather than just a nickname.
