The imaginative use of language is a hallmark of Dr. Seuss's children's books. His work is celebrated for its inventive wordplay, which includes clever rhymes, playful rhythms, and nonsensical terms that engage young readers.

Thus, the focus on inventive wordplay is what truly sets Dr. Seuss's work apart internationally.
