In this famous song from The Wizard of Oz I do not completely understand the words whiz and wiz. I think it's probably a play on words.
What is the meaning of each use of wiz or whiz?
We're off to see the Wizard
The Wonderful Wizard of Oz
We hear he is a whiz of a wiz
If ever a wiz there was
If ever, oh ever, a wiz there was
The Wizard of Oz is one because
Because, because, because, because, because
Because of the wonderful things he does
We're off to see the wizard
The Wonderful Wizard of Oz!
