"more than one book" or "more than one books"? Q: should I say "Tom has more than one book" or "Tom has more than one books"? It is likely that the single form "book" should be used as it is after "one". But I am not 100% sure. The reason why I ever considered "more than one books" is the following: As "more than one" means 2 or more, the noun following "more than one" should be in plural form. Your help will be greatly appreciated.
