An interjection is a word that comes at the start of a sentence and shows emotion but adds no information to the sentence. Common interjections are the words oh, yikes, wow, whoa, hey, well, oops
Always place a comma after the interjection before adding the rest of the sentence.
Look at these examples:
Wow, that is a big rabbit in my garden.
Oh, I didn’t realize you were here already.
Hey, we need to hurry or we’ll be late.
Always use a comma after an interjection at the start of a sentence.
It’s your turn. Place a comma into this sentence: Oops I dropped the bowl. Did you put a comma after the interjection? Good for you!
