* Onomatopoeia is the formation of a word from a sound associated with what it is named. Examples include:
* Bang
* Meow
* Sizzle
* Through is a preposition that indicates movement or passage from one side of something to the other.
"Through" itself is not an example of onomatopoeia. It doesn't imitate a sound.
Here's an example of onomatopoeia in a sentence that includes "through":
> The arrow whizzed through the air with a whoosh and hit the target.
In this sentence, "whoosh" is the onomatopoeic word that represents the sound of the arrow flying.
