Not more than one [closed]
What does “no more than one” mean in “no more than one of photophobia, phonophobia or mild nausea”? Does that mean only one out of those three or nothing at all?
Thank you very much
Solution 1:
This not a question of usage or grammar but more of logic. No more than one item taken from a list of items means taking one or none. It excludes the possibility of taking two or more.
