Which of these expresses strong emotion in a sentence?

The choice that best expresses strong emotion in a sentence is an interjection. Interjections are words or phrases, often standing alone, that convey a strong feeling or reaction, such as surprise, joy, anger, or excitement. For example, expressions like "Wow!", "Oh no!", or "Yay!" are typical interjections that immediately communicate intense emotions.

While verbs, nouns, and adjectives contribute to the overall meaning and description within a sentence, none of these parts of speech inherently carry the same level of emotional intensity as interjections do. Verbs describe actions or states, nouns identify people, places, or things, and adjectives provide details about nouns, but they do not function in the same way to evoke immediate emotional responses. Therefore, interjections are uniquely positioned to express strong emotions effectively.
