important-comma-rulesSeptember 24 is National Punctuation Day.  There are so many comma rules, I thought I’d pay homage to punctuation by reviewing a few of the rules.

Comma (,). 

  1. Use a comma to separate two complete sentences that make up a compound sentence.
  • I am washing the dogs, and I am listening to the radio.

2. Use a comma to separate items in a series whether they are words, phrases, or clauses.

  • I like extra cheese, mushrooms, and onions on my pizza.
  • I like to play the piano, bake cookies, and knit socks.

3. Use a comma after introductory words, phrases, or clauses.

  • Finally, I am going to Nova Scotia.
  • After the fair, we are going to dinner.

4. Use a comma to set off interrupters in a sentence.

  • I know, however, he is at work.
  • The blanket, which I purchased on sale, is beautiful.

5. Use a comma with quotations.

  • She said, “I’m starving.”
  • Wash the kitchen floor, Susan.
  • No, Amanda, he isn’t here yet.

6. Use a comma with contrasting elements.

  • She was small, but very mighty.
  • It was a snowy day, yet sunny.

7. Use a comma with dates and addresses (sometimes).

  • I was born on September 23, 1985, in Clifton, New Jersey, on a Monday afternoon.
  • I was born in September 198 in New Jersey on a Monday afternoon.
  • He lives at 16 Clover St., Turner, Maine 04282.
