What is the exact difference in meaning between:
- Should there not be a sign here?
- Should not there be a sign here?
- Should there be not a sign here?
My research tells me that:
- 1st - There could be a sign here, but nobody put one.
- 2nd - There should be a sign here, but nobody put one.
- 3rd - There are or is a sign here while there shouldn't be any.
