A compound sentence is a sentence that contains two or more independent clauses joined together by a coordinating conjunction (like "and", "but", "or", "so", "for", "yet", "nor").
Here's an example:
* The dog barked loudly, and the cat hissed in response.
In this example:
* "The dog barked loudly" is an independent clause.
* "The cat hissed in response" is another independent clause.
* The coordinating conjunction "and" joins the two clauses together.
