Oh, and how do you pronounce Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch?



Just the way it's spelled. That's the nice thing about Welsh, there's a one to one correspondence between the way a word is spelled and the way it's pronounced. The fact that it takes as long to explain how to pronounce the <ll> as it does to pronounce the whole word is irrelevant.
