An interjection is a word added to a sentence to convey emotion. It is not grammatically related to any other part of the sentence.
You usually follow an interjection with an exclamation mark. Interjections are uncommon in formal academic prose, except in direct quotations.
The underlined words in the following examples are all interjections:
-
-
- Hurrah! We have won the match.
- Hush ! Our principal is coming.
- Alas! We are ruined.
