Onomatopoeia
The use of words that sound like the objects they name or the sound those objects make.
Example:
"Slam! Slam! Go the car doors,
Jangle! Jangle! Go the house keys.
Jiggle! Jiggle! Go the keys in the door.
Squeak! Goes the front door!
Thump! Thump!
That is me running down the stairs
Guess what?
Mom and Dad are home!!"
All of the words that are bolded are examples of onomatopoeia.
