What is the primary purpose of an interjection?

The primary purpose of an interjection is to express emotion or emphasize a point, which is precisely what makes the chosen answer the most accurate. Interjections are typically short exclamatory words or phrases such as "wow," "ouch," or "hurray." They often stand alone or are inserted into a sentence to convey feelings, reactions, or sudden bursts of emotion, allowing the writer or speaker to convey their state of mind or to heighten the emotional impact of a statement.

The context provided by interjections can significantly enrich communication by enabling individuals to express feelings quickly and effectively. Their use enhances dialogue and adds a layer of expressiveness to both spoken and written language, aligning seamlessly with the intended purpose of conveying emotions or emphasizing sentiments.
