What is an interjection?
An interjection is a word or phrase that can be added to a sentence to express emotions, such as joy, surprise, excitement or disgust. Interjections are usually used at the beginning of a sentence. Some examples of interjections are no! oh, good, well or phew!
Some example sentences with interjections are:
Oh. I didn’t know he was going to be at the party.
Phew! I am so glad that’s over.
Good! I am so happy for you.
You got it for $25? Get out!
Ah. Now I understand
Interjections are not grammatically connected to any of the words in the sentence. Their sole purpose is to express how the speaker is feeling. This is done in a very emotional and brief way. Interjections are very rarely used in formal speech but are quite common in casual speech.
Some introductory expressions such as yes, no, indeed and well are also considered interjections.
