This is a list of the 100 most often mispronounced words.

I didn't think I would be guilty of any mispronunciation, but I just noticed that I pronounce dilate as dialate.

I have heard people talk about a boat floundering, when it is actually foundering.

I learned just a couple of months ago that it is voluptuous, not volumptuous.

It drives me nuts when people say expresso instead of espresso.

This isn't on the list, but I have heard soldiers and CNN reporters pronounce cache as cachet.
