Lyman Frank Baum, author of The Wonderful Wizard of Oz (1900) and thirteen other Oz books, also wrote many fantasies for children that did not have Oz as a setting. In all these books he liked to make up names for persons, places, and things. These names often involved word play. Puns were the most common form, but Baum also indulged in anagrams, spoonerisms, reversals, and other forms of linguistic whimsies.
