OK, if we are going to word pronunciation (or mispronunciation that I agree with RR) I defiantly have one.
Tomato - us Americans and our drive to change everything.

I just don't see why every other language that has a close pronunciation say the "a" as a short vowel. IMO
it should be a short sound on the a. It was brought to Europe from South America and both of those pronunciations use the short vowel sound for the "a" when "naming" the fruit....and the vowel - consistent - vowel rule, whatever, like that is ever followed with any consistency.
Also Coupon, where in the world is the combination of "cou" pronounced "cew" or "q." Is there such a thing as a "cewp" to keep livestock in, or of a military "cew."???? Maybe if you are playing billiards at the armory.
Last (even though there are many more) the duty pronunciation. It really bothers me when people say "doody."
And on that point, if people would just pronounce things correctly there would not be nearly as many bad spellers in this world.
I definitely classify these as pet peeves, and I take it with a grain of salt, so I don't mean to sound snotty.
