Few elements of punctuation are as daunting as the comma. When do I use it? Where do I put it? There are rules, and sometimes controversy (Oxford commas come to mind).

This month, we will focus on independent clauses.

Independent Clause plus a Dependent Clause:
Boomer, a cat who started life in the park, enjoys playing in my backyard.
The independent clause in this sentence is: Boomer enjoys playing in my backyard. This is a complete thought, with a subject (Boomer), a verb (enjoys), and an object phrase (in my backyard). As an independent clause, the above statement does not require a comma. The following clause is dependent, because it cannot stand alone: a cat who started life in the park The dependent clause is almost a parenthetical description, used to provide a little ‘background’ info on Boomer, but not essential to the main clause. When you add the two clauses togther, you need to separate them with a comma (in this case, two commas, because the dependent clause is dropped into the middle of the independent clause: Boomer, a cat who started life in the park, enjoys playing in my backyard. |
Two Independent Clauses in one Sentence:
Example: The following two clauses are independent because they can each stand alone as a complete thought: My dog is an Australian shepherd. I don’t have any sheep for him to herd. When combined, they need a comma and a conjunction (but) to connect them. My dog is an Australian shepherd, but I don’t have any sheep for him to herd.
Examples: I used to live in Montreal; however, I am not fluent in French. We discovered the thief—it was my next-door neighbor!

Great post, Susan! I have a thing about comma splices- hate seeing them, although they are increasingly common.
Thanks Lynn!
