I did it for a textbook house and they sent me a word list. That was due to the Dewey revolt in the Twenties, in which they threw out phonic reading and went to word recognition, as if you’re reading a Chinese pictograph instead of blending sounds of different letters. I think killing phonics was one of the greatest causes of illiteracy in the country. Anyway, they had it all worked out that a healthy child at the age of four can learn so many words in a week and that's all. So there were two hundred and twenty-three words to use in this book. I read the list three times and I almost went out of my head. I said, I’ll read it once more and if I can find two words that rhyme that’ll be the title of my book. (That’s genius at work.) I found ‘cat’ and ‘hat’ and I said. ‘The title will be The Cat in the Hat.’ (p. 4)
