What does interjection mean?
An interjection is a word or short phrase used to express emotion, reaction, or emphasis independently within a sentence or conversation. Familiar examples include “ouch,” “wow,” “hey,” “ah,” and “huh.” Interjections often stand alone or function as brief exclamations, though they can also interrupt a speaker to add a reaction or comment. They are especially characteristic of dialogue, informal communication, storytelling, and dramatic writing, but their register varies: “huh” sounds casual, while “alas” or “bravo” may be literary or theatrical. The same interjection can convey different meanings depending on tone and context, so punctuation and delivery are important. Although interjections are usually concise, they can communicate a great deal efficiently. Saying “aha” can reveal sudden understanding, while “ouch” immediately suggests pain. Recognising them helps readers and listeners interpret the emotional and conversational dynamics of a passage.

Interjections are the body language of words: a single “ouch” or “aha” can convey surprise, pain, delight, or realization without a full sentence.

Where does interjection come from?
The word entered English in the early 17th century from Latin interjectio, a noun formed from interjectus, the past participle of interjicere, meaning “to put between” or “throw between.” The Latin prefix inter- means “between,” while jacere means “to throw.” English later developed the closely related verb interject, and other words such as interjectory derive from the same Latin root.
