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.
Here's a quick and simple one, have you ever earmarked something to call attention to it or single it out? The word derives from an old custom for marking livestock (usually pigs) that involved nicking their ears in certain ways to indicate which pigs belong to who.
And hey, now you know.
