A list of ones I've seen in this thread or know of already:
* Nonplussed (miffed)
* Ambivalent (conflicted)
* Factoid (incorrect statement)
* Bemused (confused)
* Peruse (read thoroughly)
* Travesty (distortion)
* Transpire (to be revealed)
* Literally (in actual fact)
There's also "beg the question" which is often used to mean "naturally give rise to the question" but I believe originally meant "assumes the answer which it is trying to prove".
The modern colloquial usage of "begs the question" bugs the heck out of me. I try not to get too pedantic about language usage, but that one just sticks in my craw. I think because it's actually quite useful to understand when one is begging the question, and it feels a disservice to water down the phrase.
To be fair, I can at least see roughly why the meaning changed. The word "beg" is being used in a strange (maybe archaic?) way, and it is also useful to encode the idea of giving rise to a follow-up question. The best outcome might just be for a different phrase to capture the original meaning, something like "assumes the conclusion".
