Here's why:
* Complete Predicate: This is the part of the sentence that tells what the subject does or is. It includes the verb and any words that modify the verb (adverbs, prepositional phrases, etc.).
* Simple Subject: This is the main noun or pronoun that performs the action or is described by the verb.
* Modifiers: These are words that describe or give more information about a noun or verb.
Example:
* The big, red dog barked loudly at the mailman.
* Simple Subject: dog
* Complete Predicate: barked loudly at the mailman
* Modifiers of the subject: big, red
* Modifiers of the verb: loudly, at the mailman
In summary, the complete predicate focuses on the action or state of being, while the simple subject and its modifiers are separate elements of the sentence.
