Here are a few more comma rules, many of which you likely already know. That said, you're always welcome to make a coaching appointment if you have questions!
- Place a comma in between a city and a state and after a state (Toledo, Ohio) and between a day and a year: June 7, 2018. If you're using the military date system—e.g., 7 June 2018—no comma is needed.
- Use a comma to separate two or more coordinate adjectives—discrete adjectives that describe the same noun: big, bold book.
- Use a comma after verbs like “said” and “stated” when they introduce a quotation that is a complete sentence: Dr. Martin Luther King, Jr. stated, “I have a dream.”
- Use a comma when omitting it would cause confusion because of content. (Use sparingly.)
