Here's what makes it a compound sentence:
* Independent Clauses: These are clauses that can stand alone as complete sentences. They have a subject and a verb and express a complete thought.
* Joined Together: The two independent clauses are joined together using a coordinating conjunction (like "and," "but," "or," "so," "for," "yet," or "nor") and a comma.
Example:
* The sun was shining brightly, and the birds were singing merrily.
Here:
* "The sun was shining brightly" is an independent clause.
* "The birds were singing merrily" is another independent clause.
* They are joined by the coordinating conjunction "and" and a comma.
