Explanation

The word “dun” means “to be sweet” or “to taste good.” It is a verb describing an action or state. Verbs are not pronouns.

Pronouns are words like “I,” “you,” “we,” and “they.” They replace nouns. “Dun” does not replace a noun. It describes what something does or how it is.

Knowing parts of speech helps you build correct sentences. Verbs and pronouns have completely different functions.
