Latin interject-, participial stem of interjicĕre (-jacĕre) to throw or cast between, < inter between + jacĕre to throw
- 1: to throw in between or among other things : interpolate <interject a remark
In grammar, an interjection or exclamation is a word used to express an emotion or sentiment on the part of the speaker (although most interjections have clear definitions). Filled pauses such as uh, er, um are also considered interjections. Interjections are typically placed at the beginning of a sentence.
An interjection is sometimes expressed as a single word or non-sentence phrase, followed by a punctuation mark. The isolated usage of an interjection does not represent a complete sentence in conventional English writing. Thus, in formal writing, the interjection will be incorporated into a larger sentence clause. It also can be a reply to a question or statement.
- Examples in English
Conventions like Hi, Bye and Goodbye are interjections, as are exclamations like Cheers! and Hooray!. In fact, like a noun or a pronoun, they are very often characterized by exclamation marks depending on the stress of the attitude or the force of the emotion they are expressing. Well (a short form of "that is well") can also be used as an interjection: "Well! That's great!" or "Well, don't worry." Much profanity takes the form of interjections. Some linguists consider the pro-sentences yes, no, amen and okay as interjections, since they have no syntactical connection with other words and rather work as sentences themselves. Expressions such as "Excuse me!", "Sorry!", "No thank you!", "Oh dear!", "Hey that's mine!", and similar ones often serve as interjections. Interjections can be phrases or even sentences, as well as words, such as "Oh!" or "Wowee!".
