Over at the Economist’s Johnson blog, they’ve been running a highly unscientific but incredibly interesting survey asking British people what Americanisms they use.
Having lived and worked in the States, as well as worked for an American boss in the UK, I can attest to the fact it’s easier to acclimate than hold on to your British pronunciation. My boss took such offence to my use of the word “toilet” (as in “I’m going to the toilet”) that I still use “bathroom” even with my now all-British colleagues.
It seems that Brits living in America are still holding on to some things though, with more using “holiday” than “vacation” and “zed” rather than “zee”. To take a look at some lovely pie charts representing word comparisons, head over to the results blog post.
