What is the author's style in The Trumpet of the Swan by E. B. White?

White's style and language are specifically targeted toward children. When he uses words that he thinks the child will not understand, he explains it right in the text. The language is easy with very common words except for the names of animals. He uses the story to teach many things besides the moral lesson that is obvious. He teaches the names of the adult animal and the name of its young. He teaches the names of the male animal. His lessons are very entertaining.
