***** NOT A TEACHER *****
Good morning, 2010.
(1) "This is James's car" is 100% correct English. It is absolutely
perfect. I believe that THE NEW YORK TIMES, our most important
newspaper, still uses this kind of apostrophe.
***** BUT *****
(2) Most Americans just write: This is James' car.
(a) They think the second "s" is funny-looking & unnecessary.
P. S. When you speak, you should say "Jameses car," but
some just say "James car."
Have a nice day!
