I've always thought that if the word ends in "s" this "s" is not written in forming possessives of nouns. For instance, you write "James's hat", and I would have written "James' hat." So could you explain to me this rule, please?
I think I understand. So, if we are talking about something belonging to a concret person (We say his name), then the "s" after the apostrophe is required, but if we are talking about something belonging to a common noun (like boys, in plural), the "s" after the apostrophe is not required.
Am I right? Let me ask one more question on that. If we are talking about something belonging to a singular person or thing, a common noun, but it ends with "s", then, should we miss the "s" after the apostrophe?
It's great to have you there. It seems to me that here in Spain teachers teach the rule badly because I had exactly the same idea as Bushwhacker. I thought it was Elvis' guitar (pronounced elvisiz) instead of Elvis's. So thanks because now I've got it right. Can't wait to see my teacher's face.
