Interjections

Interjections are words used to express strong feeling or sudden emotion. They are included in a sentence - usually at the start - to express a sentiment such as surprise, disgust, joy, excitement or enthusiasm.

An interjection is not grammatically related to any other part of the sentence.

Examples:

  • Hey! Get off that floor!
  • Oh, that is a surprise.
  • Good! Now we can move on.
  • Jeepers, that was close.

Yes and No

Introductory expressions such as yes, no, indeed and well are also classed as interjections.

Examples:

  • Indeed, this is not the first time the stand has collapsed.
  • Yes, I do intend to cover the bet.
  • I'm sure I don't know half the people who come to my house. Indeed, for all I hear, I shouldn't like to. (Oscar Wilde)
  • Well, it's 1 a.m. Better go home and spend some quality time with the kids. (Homer Simpson)

Phew!

Some interjections are sounds.

Examples:

  • Phew! I am not trying that again.
  • Humph! I knew that last week. 
  • Mmmm, my compliments to the chef.
  • Ah! Don't say you agree with me. When people agree with me, I always feel that I must be wrong. (Oscar Wilde)

PUNCTUATION 

An interjection can be followed by either a comma or an exclamation mark. A comma is used for a mild interjection, while an exclamation mark is used for a more abrupt display of surprise, emotion, or deep feeling.

  • Hurry! The bus is about to leave!
  • Jeepers! That is the largest beetle I have ever seen.
  • No, I'm not going tomorrow night.
  • Well, the larva moves more quickly than you would expect.
  • Absolutely, a fifth of them do not count.
Very often (as in the first example above), an interjection with an exclamation mark is followed by a sentence with an exclamation mark.
