However, there are a few exceptions and nuances to consider:
1. Compound Subjects:
* A sentence can have multiple subjects connected by conjunctions like "and" or "or." This is called a compound subject.
* Example: "The cat and the dog chased the ball."
* Both "cat" and "dog" are subjects performing the action of "chasing."
2. Clauses with Different Subjects:
* A sentence can include multiple clauses, each with its own subject.
* Example: "The cat sat on the windowsill, while the dog barked at the birds."
* This sentence contains two clauses: "The cat sat on the windowsill" and "the dog barked at the birds." Each clause has a different subject.
3. Implied Subjects:
* In some cases, the subject might be implied rather than stated explicitly.
* Example: "Go to the store." (The subject "you" is implied)
Important Note:
* A sentence needs to have a single main subject that performs the action of the verb. While a sentence can include multiple clauses with their own subjects, there is only one main subject for the entire sentence.
