Commas
What’s the issue?
Commas help the reader understand how words are connected and used in a sentence. When commas are misused, sentence parts can run into each other, making the sentence’s meaning unclear.
Basic Comma Rules and Examples
1. Place a comma before and, but, for, nor, or, yet, or so when they connect independent clauses. (*note: commas only occur before the above conjunctions when the following clause could be a complete sentence by itself).
Ex. Perry and Della were perfect companions, yet their relationship was never romantic.
2. Place commas between items in a series.
Ex. Perry Mason was upright, sympathetic, and rotund.
3. Place a comma after an introductory element that doesn’t flow smoothly with the rest of the sentence.
Ex. After the show Perry Mason was cancelled, the world slowly deteriorated.
4. Place commas around non-restrictive elements.
Ex. My friend Ralph, who is a great cook, lives in Des Moines.
5. Place a comma before a modifying element that ends or interrupts a sentence, if that element qualifies, contrasts, or
poses an exception.
Ex. Perry’s sense of justice rules his life, a life worthy of imitation.
6. Place a comma before a tag question (if it ends a sentence) and also after it, if it interrupts a sentence. Place a comma
after or before a direct address.
Ex. You killed Gilbert Tunkle, didn’t you?
Ex. Paul, what did you find?
More Comma Rules and Examples
7. Place commas within more/less constructions.
Ex. The more cases Hamilton Burger lost, the less we pitied him.
8. Place commas between coordinate adjectives (adjectives that can be reversed without a change in meaning).
Ex. Della Street has expressive, thick eyebrows.
9. Place commas to avoid misreadings.
Ex. Just before, Perry won the case.
10. Place commas around titles.
Ex. Dr. Witherspoon, M.D., ate here.
Ex. Henry Matisse, Jr., is a little known painter.
11. Place commas within dates and geographical locations.
Ex. On Thursday, September 21, 1978, I was born.

Although women's college basketball in Connecticut is a marvelously entertaining and increasingly popular sport, it is not hard to remember when it was not so popular. Only a few years ago, my friends and I could decide on a Sunday afternoon to go to a women's basketball game at the University of Connecticut, and believe it or not, we could get seats for free near center court. Of course, that was before names such as Rebecca Lobo, Jennifer Rizzotti, Kara Wolters, and Carla Berube became household words. Lobo's book, Home-Court Advantage, which she wrote with her mother, was a best-seller for a brief time in Connecticut. If more than a couple of hundred fans showed up for a game, it was considered a big turnout, and games were played in practically silent gyms. Nowadays, it is almost impossible to buy tickets to a women's game, and you can't get seats, even in the CivicCenter, unless you know someone.
