What's the difference between "nebo" and "anebo"?
No difference in the basic usage. Both should normally be accepted. The actual preferences in each individual case and other nuances can't be explained here.
I'm wondering about that comma. Why is it there? Do you put commas before (a)nebo in czech?
We do, if the (a)nebo distinguishes two terms and only one of them is valid - exclusive or.
If both of them can be valid we do not include the comma.
