"Compound sentences are made up of two or more independent clause(s) and no dependent clauses."
Compound sentences can make your writing with more details and more information. They are made up of two or more simple sentences (independent clauses) which are the ones that have related ideas, and they are joined with a conjunction.
The independent clauses can be joined by conjunctions such as for, and, or but and a comma or a semi-colon as well. Independent clauses are two phrases that can stand alone as a complete and they do not depend one another to express an idea. However, they tie together similar ideas. The independent clauses contain three things: a subject, and action (a verb), and a complete thought.
Example of a Compound Sentence:
"María loves to bake cookies, and she is planning to bake some ginger cookies tonight"
"María loves to bake cookies" is an independent clause where "María" is the subject, "loves" is the action, and a complete thought is expressed.
"She is planning to bake some ginger cookies tonight" is an independent clause where "she" is the subject, "is planning" is the action, and a complete thought is expressed.
The Conjunction "but" is used and a comma is correctly placed before "and".
