I am confused about using the word 'so'. Here is an example.

I had a fever so I did not go to work.

Question is, in the above sentence, do I really need a comma before 'so'?

Yes. "So" is separating two sentences that could stand on their own. It would be more correct to write, "Because I had a fever, I did not go to work."


Yes, you need to use a comma before “so” when it’s acting as a conjunction to bring two independent clauses together.

You can find more information on Writer Domain here. Using that website as a reference, I created two examples for you.

The principal was sick, so he called out. — Independent, comma is needed.

The principal pretended to be sick so he wouldn’t have to go to work. — Dependent, no comma is needed.

  • Please stop using flags as an expedient to reply to my comments. If you'd like to respond, just leave a comment. You claim in your flag that these are your own words; then how do you explain this: "a comma is needed before “so” when it’s acting as a conjunction"
