Here's why:
* Verbs express actions or states of being. They tell us what the subject of the sentence is doing or experiencing.
* Example: "The dog ran across the yard." (action verb)
* Example: "The flowers are beautiful." (state of being verb)
* Other parts of speech may describe or modify the action, but they don't express the action itself.
* Nouns: Name people, places, things, or ideas (e.g., "dog," "yard")
* Adjectives: Describe nouns (e.g., "beautiful")
* Adverbs: Describe verbs, adjectives, or other adverbs (e.g., "quickly," "very")
