Are you a comma criminal? Do you steal commas from places where they really need to stay? Or maybe you’re a comma enthusiast and stick them in wherever you “feel” they need to be? If you said yes to one or both, you’re not alone. When it comes to commas, most people don’t go by any solid rules. Not only can that make your sentence structure inconsistent, it can confuse your readers about what you’re trying to say.
It’s comma time again. I know. Try to contain your groans. We’re almost done! In this fourth part of the series, we’ll talk about pauses, sentence clarification, places, people, dates, words at the end of a sentence, and dialogue. And yes, it’s going to be easier than it sounds. Once you get the hang of commas, using them will come more naturally. I promise.
Have you missed any of the first three installments? No worries. Click on the links below to catch up. Here’s a quick guide if you’re looking for something specific.
- To Comma, or Not to Comma (Part 1): Part 1 covers general comma abuse, dependent and independent clauses, plus everything else you thought you didn’t need to know about sentences, clauses, and predicates.
- To Comma, or Not to Comma (Part 2): Part 2 covers essential and unessential information, “that” clauses, and names.
- To Comma, or Not to Comma (Part 3): Part 3 covers adjectives, including size, color, and number, and the dreaded Oxford (serial) comma.
Take a Pause
Sometimes, even if we follow the comma rules, the meaning of words in a sentence can be unclear or need some contrast. Especially when those words fall at the end.
Incorrect: He’s just being quiet silly.
This literally means he’s being “quiet silly.” Which isn’t really a thing.
Correct: He’s just being quiet, silly.
Incorrect: He was only distracted not stupid.
Correct: He was only distracted, not stupid.
As a general rule, use a comma before “not” at the end of a sentence.
Incorrect: Our robotic math professor seemed different today almost human.
Correct: Our robotic math professor seemed different today, almost human.
Incorrect: That’s John’s new car isn’t it?
Correct: That’s John’s new car, isn’t it?
Sentence Clarification
Commas come in handy if there’s ever an issue with understanding what a sentence means.
Incorrect: Jeremy gestured at the herd of stampeding horses yelling wildly.
Above, the horses are yelling wildly, not Jeremy. But with a comma added in the right place below, it becomes clear that Jeremy is the one yelling.
Correct: Jeremy gestured at the herd of stampeding horses, yelling loudly.
Places, People, Dates
Use commas to set off specific geographical places and addresses, people’s titles, and dates.
Examples of Places:
- Dallas, Texas, is where I’m from.
- I used to live in Madison, Wisconsin, before I moved.
- My sister lives at 676 Maple Lane, Plano, Texas.
Yes, you need a comma after the state too if it’s not at the end of the sentence. The odd way it looks throws many people off.
Examples of Titles:
- My primary care doctor is Glenda Green, MD.
- Glenda Green, MD, is my primary care doctor.
Examples of Dates:
- September 11, 2001, is a date no one will ever forget.
- May 18, 1943, was the day my mom was born.
Yes, you need a comma after the year too. Even though it seems weird.
Exception: There is no comma with just the month and year—unless the date is used an opening clause.
- I married my husband January 1991.
- In January 1991, I married my husband.
TOO, ALSO, EITHER at the end of a sentence
Just like we no longer type that extra space after a period, we can scratch that comma before too, also, and either, providing the words come at the end of a sentence and the meaning is clear.
Correct: Keep the comma.
- I, too, like fruit.
- I, also, like fruit.
Correct: Ditch the comma.
- I like fruit too.
- I like also.
- I don’t like fruit either.
Dialogue
Finally, something most writers are familiar with—dialogue. There’s a simple rule here. We always use commas to set off dialogue. That’s it.
But remember dialogue means what your characters say out loud. It’s external. We’re not talking about the thoughts inside their heads. That’s internal and doesn’t need quotes either. See my post on Dive Deep into Dialogue for, well, a deeper dive into dialogue.
Incorrect: Jean said I’m not hungry. / I’m not hungry Jean said.
Correct: “I’m not hungry,” Jean said. /Jean said, “I’m not hungry.”
A Final Hint
Use commas when your reader will be confused without them.
Incorrect: To George Lucas was the father of Star Wars.
Because the two names, George and Lucas, usually belong together, we read them as if they are together. But that’s not what the writer of this sentence meant.
Correct: To George, Lucas was the father of Star Wars.
We’re done. You made it! I hope you walked away from this comma series with some concrete takeaways. I’d love to hear them. What have you struggled with? What did you learn? Do you have any comma advice to share? And what other punctuation would you like me to cover? I love requests as much as I love your comments.
