* Complete Subject: The complete subject includes the simple subject (the noun or pronoun performing the action) and any words that modify it.
* Prepositions: Prepositions introduce prepositional phrases, which function as adjectives or adverbs, modifying nouns or verbs. They do not act as the subject of a sentence.
Example:
* "The cat on the mat" is the complete subject.
* "Cat" is the simple subject.
* "On the mat" is a prepositional phrase modifying the noun "cat."
Why it Matters:
Understanding the structure of subjects and prepositional phrases is crucial for analyzing sentence structure, identifying the main idea, and understanding how words work together.
