Johnson has had a couple of posts lately about the ways in which British and American English influence each other. This, in particular, discusses the ways in which British expats adopt American terms and pronunciations, to either pride or chagrin, and invited readers to take an informal survey on their use of language. The results are here:

It seems that “sidewalk” and “apartment” are the two commonest adoptions, while about half of you use “vacation” and “bug”. There’s a bit more resistance to “I’m good” over “I’m well”, and to saying Z as “zee” instead of “zed”. Around two-thirds stick with the British pronunciations of “process” and “progress”, which seems to confirm my suspicion that those two are real assimilation watersheds. Interestingly, over 40% are, like me, stuck somewhere between the American and British pronunciations of “beta”.

Full write-up at the link, as always, with some lovely graphs. I got a kick out of this, you might, too.

If you think it’s just American English changing the way Brits speak, you’ve got another think coming. Not One-Off Britishisms is a fun blog dedicated to expressions with origins in the UK that have snaked their way into US parlance.
