An interjection is a part of speech used to convey or express sudden feelings and emotions. It is a word or phrase that is grammatically independent from the words around it, and mainly expresses feeling rather than meaning.

Interjections are short exclamations like Oh!, Um or Ah! They have no real grammatical value but we use them quite often, usually more in speaking than in writing.

Examples

• Oh, what a beautiful house!
• Uh-oh, this looks bad.
• Well, it’s time to say good night.
• Hurray! We won the match.
• Ouch! That really hurt badly.
