Assonance

Definition:
My definition of assonance would be "the same vowel sounds with different constants".

Example:
"Now I know, that I had to borrow
Beg & steal & lie aint' cheap
Trying to keep you, trying to please you
Cause being in love with your face ain't cheap."
- Cee-Lo Green

Significance of the Term:
It's important to know this word because we can use other words or find new words that rhyme with the vowel sounds.

Picture:

^ "Little Bo-peep has lost her sheep,
       And can't tell where to find them;
       Leave them alone, and they'll come home,
       And bring their tails behind them."
