Here's why:
* Simple Predicate: The simple predicate is the verb or verb phrase that tells what the subject does or is. It's the core action of the sentence.
* "Do Not" is a verb phrase acting as an auxiliary verb (helping verb). It combines with the main verb to create the complete predicate.
Example:
* Do Not eat the cookies.
* Do Not is the auxiliary verb.
* Eat is the main verb, forming the simple predicate.
* Do Not eat is the complete predicate.
Therefore, "Do Not" itself is not the simple predicate. It is a part of the complete predicate.
