Which of the following parts of speech expresses emotion?

Verbs primarily indicate actions, states, or occurrences rather than emotions. While some verbs can express feelings when used in context (like "love" or "hate"), they do not inherently convey emotion on their own. Their primary function is to describe what the subject is doing or experiencing rather than expressing an emotional response.

Adverbs modify verbs, adjectives, or other adverbs, often describing how an action is performed. While they can enhance the emotional tone of a sentence (e.g., "happily" or "sadly"), adverbs do not express emotion independently. Their role is to provide more detail about the manner or extent of actions rather than to convey feelings directly.

Pronouns serve as substitutes for nouns and do not have inherent emotional value. They are used to avoid repetition and maintain clarity in sentences. While pronouns can be involved in emotional contexts (like "I" in "I am sad"), they do not express emotion by themselves; their function is grammatical rather than emotional.
