Definition: Alliteration means the first sound of a series of words are the same.
Example: "I am what I want you to want, what I want you to feel."(Lyrics.com, Linkin Park, Faint)
Explanation: This is an example of Alliteration because the first sound of a series of words in a phrase have the same sounding beginning. "What I want you want" all have the same starting letter, which qualifies this phrase to be alliteration. When a song writer uses this term it creates an amazing affect. What it does is make the sentence or phrase flow.
