Mischievous (almost always mispronounced "mis-CHEE-VEE-us")

I am guilty of this, LOL.

One of the ones I hear quite often is "real-li-tor" instead of "realtor." Often by Realtors themselves!

In a similar vein, enormity does not mean simply big.

Mis-CHEE-VEE-us and REAL-a-tor (and others that don’t come to mind right now) are an assault to the ears. It’s especially maddening when someone who really should know better (an English teacher, an actual realtor) does it. I feel like it’s a evil plot to drive me nuts!
