I've got a collection of random information in my brain that makes me an awesome Trivial Pursuit partner, but is completely useless when it comes to real world application. Like say, job applications.
I thought I'd share some of this random crap with you in the form of another acronym-ific series. I give you - Word Origins from Left Field - that's right, the WOLF. Er... ignore the fact that the "from" doesn't fit.
It's a phrase most of us hate, and none of us understand:
The exception proves the rule.
No, it doesn't make sense... unless you understand the history of the word proves.
The word proves was more commonly used as meaning; to test the truth or usefulness of something - think proving ground.
So the exception proves the rule means that the exception is testing the rule... not providing proof that it is, in fact, a rule.
