HI everyone, I was wondering if i could get a definitive (or as close to definitive as possible) answer to the question of whether to put a comma after "then" when it starts a sentence.
First, listen to the CD. Then answer the questions.
OR
First, listen to the CD. Then, answer the questions.
I've looked online and there doesn't seem to a be consensus. Some sites say that all sequence words, including "then" must be followed by a comma, while others say that all sequence words, except for "then" take a comma. Could someone give me an answer with a respected source (a la CMS) so that i can have it in my corner when someone says "OOOOO you can't use a comma there" etc.
Thanks in Advance
