Compound Sentence with Coordinating Conjunction

Now that you have seen the four sentence patterns, you will learn more about each one. A compound sentence is composed of two independent clauses; each of the two clauses could stand alone as a sentence. When the two independent clauses are joined by a coordinating conjunction, the sentence needs a comma before the conjunction. (The coordinating conjunctions are and, but, or, nor, for, yet, so.)

The pattern looks like this:

Compound sentence with coordinating conjunction

Note: In a compound sentence, each part of the sentence is an independent clause. That is, each part has its own subject and verb, and each part could stand alone. When there is only one subject and two verbs, do not use a comma between the verbs.

One subject and two verbs: not a compound sentence

Incorrect—with comma:
