Eleven letter word

Here is a riddle for you:

There is an 11-letter word in the English language that is pronounced incorrectly by over 99% of the population. What is this word?

Unfortunately, I do not know the answer, so I'm hoping someone can help me out! My friend knows the answer but won't tell me, the most I've got out of her is that it's on this page: http://www.aivazoglou.gr/11.html although that is basically useless... oh yeah, it's also starts with a letter from the first half of the dictionary.

Thanks!!!
