What is the correct possessive for nouns ending in s?
When did it become correct to add an 's' to a singular possessive already ending in 's'?
I always had this difficulty understanding how to depict possessive nature for words ending with s.
For example: Is it correct to say, "James's heart is made of gold"? Or is there any other way to use apostrophes with words ending with S?
