Step-by-step explanation:
When we have a single independent clause, we have a simple sentence. An independent clause is a group of words that has a subject and a predicate and that expresses a complete thought.
A compound sentence is what we have when we join two independent clauses. To do so, we need to use coordinating conjunctions, which are: for, and, nor, but, or, yet, so.
Finally, a complex sentence is what we have when we join an independent clause and a dependent one. The dependent clause starts with a subordinating conjunction, such as "although" or "so that".
