Son of "Words that Piss Me Off"
Until I actually study the English language, I suppose this is going to become a regular A19 feature (see here). Last night on some cable news, I heard the word "potentiality." Seems to me there is no reason whatever for the existence of this word, though it is in the dictionary. I will relent if anyone can give me an example of a sentence using the word "potentiality" where "potential" wouldn't work just as well.

Doug, what does your big dictionary say about this one?
