A compound sentence has two or more independent clauses connected by a coordinating conjunction. Common examples of coordinating conjunctions are: and, but, or, nor, for, yet, so.A complex sentence has a main clause and one or more dependent clauses. In a complex sentence we use a subordinating conjunction to connect the dependent clause to the main clause. Common examples of subordinating conjunctions are: as, when, while, because, since, after, before, although, though, if, whether, unless and until.
We can change a compound sentence into a complex sentence by replacing the coordinating conjunction with a subordinating conjunction. Study the examples given below.
