Simple Subject
* Definition: The main noun or pronoun that performs the action of the verb in a sentence.
* Example: *The cat* sat on the mat. (The simple subject is "cat")
Compound Subject
* Definition: Two or more simple subjects joined by a coordinating conjunction (and, but, or, nor, for, yet, so) that together perform the action of the verb.
* Example: *The cat and the dog* chased the ball. (The compound subject is "the cat and the dog")
Key Differences:
* Number of Subjects: A simple subject has one subject, while a compound subject has two or more.
* Conjunctions: Compound subjects are joined by coordinating conjunctions, while simple subjects are not.
* Function: Both simple and compound subjects perform the same function: they are the doers of the verb.
Here's a helpful tip: To identify the subject, ask yourself, "Who or what is doing the verb?" The answer will be the subject.
Let's look at more examples:
* Simple Subject: *The sun* shines brightly.
* Compound Subject: *My brother and I* went to the movies.
* Simple Subject: *The old house* stood on the hill.
* Compound Subject: *Apples, oranges, and grapes* are healthy fruits.
