Here’s Part 2 of the Comma Rules. There’s only a few left, but they can be a bit tricky for some of us. If you missed, COMMA, COMMA, COMMA CHAMELEON: COMMON COMMA RULES, PART 1, please go back and read through it as well.
General Comma Rules, con’t:
* A comma should follow expressions:
namely, for example, that is, for instance, especially.
- Some members of the political party plead guilty; namely, Chester Dester, Lucy Lurker, and Tony Baloney.
- I love European chocolate; especially, dark chocolate.
* A comma is used to introduce a quotation OR to complete a quotation that does not conclude the sentence.
Note: Commas and periods are placed “within” the quotation marks.
- Lucky’s teacher said, “It’s raining out there.”
- “But I really don’t mind the rain,” Lucky replied.
Note #2: Commas should not be used to introduce indirect quotations.
- Lucky answered that he did not mind the rain.
*If you need a mild exclamatory, you can use a comma instead of an exclamation point.
-Well, I don’t mind the rain.
Commas in Addresses:
Addresses in block form:
* Use a comma after a name if it is followed by a title and between titles if there’s more than one.
* Use a comma between a city (or county) and its state.
* Do not place a comma between a state and its zip code.
