Pronunciation
I am very fascinated with the pronunciation of words.  I often ask my friends how they pronounce certain words, such as:
celtic
mirror
poor
era
data
neither
either
presentation
sure
hostile
futile
tomato
potato!!

I have a very interesting story about the word "bury."  Most people pronounce it "berry," correct?  Well, a few years ago my school made the annual trip to Washington, D.C, specifically Arlington Cemetery.  Our tour guide kept pronouncing it "burry."  It drove us insane!  To this day, we still talk about it.

Do you have a word with a disputed pronunciation?
