What does interjection mean?

An interjection is a word or phrase that expresses something in a sudden or exclamatory way, especially an emotion. Yikes, uh-oh, ugh, oh boy, and ouch are common examples of interjections.

In grammar, interjections are considered one of the parts of speech (types of words categorized by function, like nouns and verbs and adjectives).

Interjection is the noun form of the verb interject, which most commonly means to interrupt or insert a comment. Interjection can also be used to mean the act or instance of doing so, as in Can I make an interjection?

Example: There was a chorus of angry interjections when the people in the audience heard that their taxes would be going up.

Where does interjection come from?

Use of the word interjection in English actually precedes the use of interject. The first records of interjection come from the 1400s, but interject isn’t recorded until the late 1500s. (Of course, interjections themselves have been used for far longer than that.) Interject comes from the Latin interjicere, meaning “to throw between,” from inter, “between,” and jacere, “to throw.”

A lot of interjections express feelings, like surprise (whoa, wow), disgust (ew, yuck, ugh), frustration (good grief), or excitement (yay, oh boy). Some interjections express requests or demands, like shh, hush, and ahem. Some indicate pain (ouch) or disappointment or dismay (d’oh). Other interjections are used to react to a realization or something someone has said, like aha, eureka, bingo, and duh. Still others are used to get someone’s attention, like hey and yo.

In grammar, interjections usually stand alone, meaning they are often separate from a sentence, as in Ouch! I stubbed my toe. That’s because they express something all by themselves—they don’t need nouns or verbs to complete the thought.

In more general terms, an interjection is a comment inserted into an ongoing discussion. An interjection can be an interruption, but interjections are a normal part of conversation.
