"Language play, the arguments suggest, will help the development of pronunciation ability through its focus on the properties and sounds and sound contrasts, such as rhyming. Play with word endings and decoding the syntax of riddles will help the acquisition of grammar. Readiness to play with words and names, to exchange puns and to engage in nonsense talk, promotes links with semantic development. The kinds of dialogue interaction illustrative above are likely to have consequences for the development of conversational skills. And language play, by its nature, also contributes greatly to what in recent years has been called metalinguistic awareness, which is turning out to be of critical importance in the development of language skills in general and of literacy skills in particular."
