If you’re watching a good British comedy, and are confused by someone who’s “knackered” or don’t know why someone would “snog” someone else, have I got a site for you.

The English-to-American Dictionary is a great site set up by a Scot named Chris Rae who’s spent some time in America and started cataloging words that are unique or different between cultures.  There’s a category index and an alphabetical index, as well as things about date formatting, currency and the like.  It’s a great reference and fun just to poke around and read too.
