Writers often play with the sounds in words. For example, if they are finding a name for a cartoon character, they might:
-repeat the first sound, for example Donald Duck.
-repeat the first sound or sounds (this is called rhyme), for example Ronald McDonald.
Listen to these examples of names and expressions with sound-play. Notice that the writer is playing with the sound, not the spelling. For example, in Dennis the Menace, the last three sounds of the words are the same, but the spelling is completely different.
