I just discovered this thread, and am soooo looking forward to reading it! No time now, must zip over to the Y to swim before the guppies invade (little kid swim time). But I'll throw out some of my most loathed words:

Operationalize. NO! WRONG! NOT A WORD!

Impact. Correct if you mean "one object hit another. There was an impact." Or, "the patient can't poop."
BUT NOT TO BE USED AS A VERB! "It really impacted me." NO! WRONG!

Thank you. Having thus vented my spleen, I'm off to swim.
