What is the difference between 'c'est un bon garcon' (sorry can't do the circumflex) and 'il est un bon garcon'? I'd have thought that 'c'est un bon garcon' meant 'there is a good boy' rather than 'he is a good boy'.
yeah, I thought that was a rule, too. I just looked it up and if falls under "Modified and unmodified noun." Those are interchangeable. If is was Il est fort, an adjective, it would have to be "Il est".
