Here's why:
* Verbs are words that express actions, states, or occurrences. "Describe" means to explain or give an account of something.
* Adjectives are words that modify nouns or pronouns, providing more information about them. They often answer questions like "what kind?" or "which one?".
For example:
* Verb: "I will describe the painting to you."
* Adjective: "It's a beautiful painting."
