(teach) Re: Differences Between American and British Grammar

There are differences but I don't know of a good website and the differences are relatively minor. Another problem is that there are many US and UK grammars. It's not a case of looking at just two. I'd say that the most likely one for learners to come across concerns present perfect, a nightmare tense anyway. I don't think I'd like to make it any more complicated for learners. I teach UK usage and just say that many americans use present perfect less.

US tends to be "I did it already" while UK tends to say "I've done it already.
