What is interjection
An interjection is a word or phrase that expresses sudden or strong emotion or sentiment. Interjections are often used independently and can convey a wide range of feelings such as surprise, joy, excitement, disgust, or frustration. They can stand alone as a complete utterance or be inserted within a sentence to convey the speaker's emotional reaction.

Examples of interjections include:

- "Wow!"
- "Ouch!"
- "Hey!"
- "Oh no!"
- "Hurray!"
- "Oops!"
- "Ah!"
- "Bravo!"

Interjections add color and expressiveness to language, allowing speakers to convey their emotions more vividly in conversation or writing.
