Onomatopoeia is defined as a word, which imitates the natural sounds of a thing. It creates a sound effect that mimics the thing described, making the description more expressive and interesting. For instance, saying, “The gushing stream flows in the forest” is a more meaningful description than just saying, “The stream flows in the forest.” The reader is drawn to hear the sound of a “gushing stream” which makes the expression more effective.

The buzzing bee flew away.The sack fell into the river with a splash.The books fell on the table with a loud thump.He looked at the roaring sky.The rustling leaves kept me awake.
