What two independent clauses are called when they joined together correctly?

When two independent clauses are joined together correctly, they are called a compound sentence.

Here's why:

* Independent Clause: A complete thought that can stand alone as a sentence.

* Compound Sentence: A sentence made up of two or more independent clauses joined by a coordinating conjunction (like "and", "but", "or", "nor", "for", "so", "yet") or a semicolon.

Example:

* Independent Clause 1: The sun was shining.

* Independent Clause 2: The birds were singing.

* Compound Sentence: The sun was shining, and the birds were singing.
