Here's a breakdown:
* Function: Expresses strong emotion or feeling
* Placement: Usually stands alone, separate from the main sentence
* Punctuation: Often followed by an exclamation point (!)
* Examples:
* Wow! That's amazing!
* Ouch! That hurt!
* Hey! What's going on?
* Goodness! That was close.
Interjections can express a wide range of emotions, including:
* Surprise: Wow!, Oh!, Goodness!
* Pain: Ouch!, Yikes!
* Happiness: Yay!, Hooray!
* Anger: Darn!, Shoot!
* Disbelief: Well, I'll be!
Remember: While interjections are often informal, they can also be used in more formal writing to add emphasis or emotion to a sentence.
