Oh, lord, thesaurus finger is the bane of my existence. I had one gal who used "intercession" as a synonym for "intervention" --- when talking about JS Mill --- and repeatedly wrote things like this: (note, this is taken verbatim from her paper) "When intercessing in another country, the people of the country intercessing should make sure they have a criteria for going intervening."

What the hell does that say, and when did criteria become singular? I also had another student who argued that presidents declare war all by themselves. Okay, I don't do political science, and even I know that's wrong!
