Definition & Meaning of "interjection"

What is an "interjection"?

An interjection is a word or phrase that expresses a strong emotion or reaction and is often used independently from the main sentence. Interjections can convey a wide range of feelings, such as surprise, joy, anger, or excitement. Common examples include "wow," "ouch," "hey," "oh," and "hurray." Interjections are usually followed by punctuation, such as an exclamation mark, to emphasize the emotional response. For instance, in the sentence "Wow! That is amazing," the interjection "wow" shows excitement. Understanding interjections is important for recognizing how emotions are conveyed in speech and writing, adding depth and expressiveness to communication.
