Tyke51, I'm quite ambivalent about Americanisms. I used to think, 'why should I use - or even have to hear - their word when English has a perfectly good one of its own?' I then reminded myself that language evolves over time, and also that the dominance of American culture certainly has had an influence on vocabulary. As Spoffy said on another thread, we've accepted words such as 'duvet', 'kaput' and 'junta' from other languages. If Americanisms are accepted by, and used by, many of us, are they really so wrong?
Having said all that, there are, of course, Americanisms that we all particularly dislike. I don't mind your 'elevator', but I'm not a fan of 'sidewalks'.
