Alleviating Comma Trauma!
Many people suffer from “comma trauma”—the sense of panic that sets in when trying to determine whether or not to use a comma in a sentence. Much of the confusion arises because of the way we were taught commas in grade school and high school. “Put a comma where you would pause” is one well-intended “rule”; apparently, some people pause in strange places, leading to what I refer to as “comma compulsion”—putting commas after every word or two. Personally, I would rather see a few missing commas than a proliferation!
Whether you suffer from “comma trauma” or “comma compulsion,” here are some basic guidelines that might help:
1. Use a comma after introductory words (Yes, No, Well,). (But please don’t start a sentence in formal writing–academic or business–with “Well.” That’s just wrong.)
Yes, I saw that show last night.
No, we’re not going out to dinner with you.
Well, I’m sure he didn’t mean what he said.
2. Use a comma after introductory phrases and clauses.
After the concert, Elvis left the building.
In case you hadn’t heard, the meeting starts promptly at 9 a.m.
3. Use a comma to set off an adjective or adjective phrase from the noun it modifies.
Mr. Brown, our company’s vice-president, presided at the meeting.
4. Use a comma to set off a direct address.
Susan, will you bring that report with you to the meeting?
Are you sure those figures are correct, Mr. Jones?
I’m sorry, Tom, but your department’s budget hasn’t been approved.
5. Use a comma to set off parenthetical expressions (a qualifying or explanatory phrase).
It’s important, by the way, that you complete the assignment on time.
The toaster, which we received as a wedding gift, never worked properly.
6. Use a comma after each item of a date, address, or geographical location. Do not use a comma when the date is just the month and year (February 2010). The address number and street name are one item. The state and zip are one item. The month and the day are one item.
My office is at 123 Nowhere Blvd., Fledgling, MO 51111.
We got married on August 24, 1968.
(NOTE: If the city and state appear in the middle of a sentence, use a comma after the state, too: In St. Louis, Missouri, the Arch is the biggest tourist attraction.)
7. Use a comma to set a quotation off from the rest of the sentence.
Franklin D. Roosevelt said, “We have nothing to fear but fear itself.”
“It’s only fair,” James said, “that I split the household chores with Margaret.” (NOTE: In the U.S., periods and commas ALWAYS go inside quotation marks.)
8. Use a comma to separate two independent clauses (complete sentences) joined by a conjunction.
I went to Florida last year, and I am going again this year.
You must finish your dinner, or you won’t get dessert.
9. Use a comma to separate items in a series.
The desk drawer contained paper, pens, markers, and a ruler.
I took a shower, dried my hair, and put on makeup. (NOTE: It’s really “personal preference” whether to use a comma between the second-to-last and last item in a series. Do whatever you want; just be consistent within a document.)
10. Use a comma to separate titles and degrees from the names they’re associated with.
Mary Smith, Ph.D., will address the audience.
11. Use a comma for clarity.
In the winter, days are shorter.
High above, the sun shone brightly.
While playing, the girl fell and skinned her knee.
12. Use a comma in place of omitted words.
I played piano; Terri, guitar. (Terri played guitar.)
This list of guidelines isn’t all-inclusive, but it should help you avoid some of the comma trauma drama that prevents you from being the best writer you can be.
