Comma with Compound Sentences

Jared Aragona

Comma with compound sentences: Use commas to separate independent clauses when they are joined by any of these seven coordinating conjunctions: and, but, for, or, nor, so, yet.


Everyone in the class got a study guide, and I need a study guide too.

(Notice how the underlined clauses could be their own complete sentences?  When that’s the case on both sides of the conjunction, use a comma before the conjunction.)


DO NOT use a comma if there is not a new subject in the second clause. (H13)

John felt he could finish his work and still be home for dinner that night.



H1-XIn most cases, don’t put the comma after the coordinating conjunction in a compound sentence.  The comma goes before the conjunction. 

I like flying, but I prefer to drive.  (Correct)

I like flying but, I prefer to drive.  (Incorrect)
