One of my favorite topics! Although I have never lived in Britain, I have visited there many times, spending about 5 months total. Whole books have been written on the subject of our language differences, and I have about three of them-I will look them up if anyone cares.

Here's a question that has puzzled me: Brits say "Christian name" where Americans would say "first name" and "surname" where Americans would say "last name," - for example, when bureaucrats are filling out a form. It's easy enough to understand what you mean, but-how do you address a Muslim? Wouldn't it be offensive to ask him what his "Christian name" is?
