Oh Say Can You Say? is a vocabulary-building experience. It is only by encountering new words that a child increases his or her vocabulary. In this book Dr. Seuss has placed a treasure trove of word sounds within every child’s reach — tonguetickling vignettes of sense and nonsense that he dares his young readers to say aloud. And in doing so, they will profit from their attempts.
