Assonance is the repetition of vowel sounds within a sentence or passage of writing. For example:
Joe is away from home and is lonely.
In this example, the "o" sound is repeated in three of the words in the sentence.
In The House on Mango Street, we find the following examples of assonance:
Out back is a small garage for the car...and a small yard... [the "ah" sound is in the words small, garage, and yard]
Do you like these shoes? But the truth is it is scary to look down at your foot... [the long "u" sound is in the words shoes and truth; the short "u" sound is in the words lookand foot]
In The Joy Luck Club, we find these examples:
“Now you see,' said the turtle, drifting back into the pond, 'why it is useless to cry. Your tears do not wash away your sorrows. They feed someone else's joy [the long "e" sound is used near the beginning of each of these three sentences].
“I had on a beautiful red dress, but what I saw was even more valuable. I was strong. I was pure [the long "u" sound is in the words beautiful, valuable, and pure].
