1. What is an Interjection?
An interjection is a word or phrase used to express strong emotion, surprise, or reaction.
It is often followed by an exclamation mark (!) or a comma (,), depending on the intensity.
Examples:
-
Wow! That’s amazing!
-
Oh, I didn’t know that.
-
Yikes! That looks painful.
-
Hmm, I’m not sure about that.
 Interjections stand alone or at the beginning of a sentence and are not grammatically connected to other parts of the sentence.
