secondary interjection

In English grammar, an interjection is a word or phrase used to express an emotional reaction or to emphasize a thought. Interjections are grammatically separate from the rest of the sentence and can often be removed without changing the sentence's core meaning.12

There are two main types of interjections:
* Primary interjections: These words function only as interjections (e.g., oops, yikes).1
* Secondary interjections: These words can function as other parts of speech but are used as interjections in certain contexts (e.g., Congratulations!, Never!).1

Interjections are common in speech and informal writing, adding color and emphasis, but are used sparingly in formal contexts. They can express a wide range of emotions, such as surprise, disgust, shock, happiness, agreement, or disagreement.12
