Continuing on with the list of comma rules:
Comma Rule #6: When an expression or a conjunctive adverb is embedded within a sentence, they should be set off with commas.
Example: Mary and John, wouldn’t you know, ran off together to the writers’ conference. We should, therefore, be ready to learn all we can from them when they return.
Comma Rule #7: When a sentence is directed toward someone, that person, however addressed, is set off by commas:
Example: John, did you enjoy the conference.
Where have you been, sweetheart?
Comma Rule #8: A comma follows exclamations as well as yes and no when starting a sentence.
Example: Oh, you didn’t? Yes, you did. Yikes, are you ever in trouble.
Comma Rule #9: Adverbs that introduce a sentence are followed by a comma.
Example: Obviously, you were oblivious to the trouble in which you found yourself.
Comma Rule #10: When writing out city and state, month, day,and year in a sentence, the second item is set off by commas.
Example: Drew was born in London, England, on October 9, 1979, but his family moved to New York on January 1, 1981.
