Here is a sentence that is confusing me:
I don't like stories that have unhappy endings.
I am confused about the usage of the plural noun 'endings'. I think a story normally has only one ending. So it's more natural for me to say '... stories that have an unhappy ending'.
I are not sure whether the plural noun 'endings' here is used to mention a particular kind like 'Dogs are animals'. Are the plural version and the singular version have the same meaning? Or the writer of the sentence wanted to imply a story may have multiple endings?
