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:
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.
An interjection can be followed by either a comma or an exclamation mark. A comma is used for mild interjection, while an exclamation mark is used for a more abrupt display of surprise, emotion, or deep feeling.
Examples:
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.
Interjections do not always have to come at the beginning of a sentence either. For example, if you said "So, you don't like spinach too much, huh?" "Huh" would be the interjection at the end of that sentence, designed to convey the emotion or confusion (or perhaps sarcasm or dismay at the dislike of spinach).
Interjections can even be found right in the middle of a sentence. Example: "When I think about the number of interjections in English, good gracious, I don't think I could ever list them all." In this case, "good gracious" is the interjection, designed to convey your amazement at the number of interjections, or you dismay at the prospect of listing them all.
The list of interjections used in English is extremely long, just as the list of adjectives or adverb would be. Almost any word or phrase can be used as an interjection, if it is inserted into a sentence to convey an emotion. For example, if you hurt yourself, you might say "Damn! That hurts!" Damm would be the interjection. You could, however, also say "Ouch! That hurts!" Or "Damm! That hurts." Or "Gee! That hurts!" or..... well, as you can see could go on and on.
