Ireland is a tough one when abroad, particularly the US - if you don't pronounce it the way truthseeker has spelt it above, they can have difficulties understanding. There are also lots of pronunciations even here - ire/eyer/eye-uh (r barely heard)/are(rhyming with car)/oy-er following by lind, lund or land. And there's probably others too. Not sure which is correct to be honest...The customers would say 'Lite EYE-taalian? Youre from Eyerland arent you?'
Update: Sky News have the Queen visiting Eye-land
