This has been a bugbear of mine for ages and I've never been able to figure it out.
Whilst we can perhaps excuse common words like 'aluminium' on the grounds of regional variance, there really is no excuse for pronouncing names wrong. The only Americans I heard get Novak Djokovic's name right during the whole US Open were the ones working for the BBC. And Notre Dame is another one that often bugs me. Now I appreciate that learning how to pronounce words from other languages/countries can be tricky, but over here we generally make the effort to at least try (even if it's just so we can say the name of our latest foreign footballers or to stop the French sneering down their garlicky noses at us). Americans don't seem to bother and I'm curious as to why. Do you not realise you are saying them wrong or do you simply just not care? Any trans-atlantic explanations gratefully received.
