Here's why:
* Predicate: The predicate of a sentence tells us something about the subject. It usually includes the verb and any objects or modifiers that complete the thought.
* Simple Predicate: The simple predicate is the core of the predicate, containing the verb and any words that directly modify the verb (adverbs, for example).
* Verb: The verb is the action word or state of being in a sentence. It is essential for making a statement.
Example:
* Sentence: The dog ran quickly.
* Predicate: ran quickly
* Simple Predicate: ran
Therefore, the verb is the word that forms the simple predicate.
