Here's why:
* Onomatopoeia is the use of words that imitate the sounds they describe. Examples include "buzz," "crash," "meow," and "tick-tock."
* "Smacked" and "wacked" are more descriptive words that evoke the impact of a hit or blow, but they don't directly imitate the sound.
Think of it this way:
* Onomatopoeia: "The ball went *thump* when it hit the wall." (The word "thump" actually sounds like the impact)
* Descriptive words: "He was *smacked* in the face." (The word "smacked" doesn't sound like the hit, but it describes the action)
Therefore, while "smacked" and "wacked" are related to sounds, they are not onomatopoeic words.
