Mole

The word 'mole' is so marvelously, multiply layered. Many of my fine readers are probably aware of at least three different definitions of the word 'mole' straight off the tops of their heads... But wait! There's more! For the vast definition of the word 'mole', go here. To sum it up for you lazy people who don't feel like clicking a single link and then searching through oodles of text, here is an abbreviated version of what dictionary.com has to say:

1. A burrowing, furry insectivore with powerful front paws for digging, with little or no eyesight. (This would be the only true thing about all moles...)
2. Machine built for drilling/tunneling underground
3. Artificial structure built to shelter a harbour (Also known as, for whatever reason, a groin, among other things. They're those bits that stick out of beaches/cliffs, for example. These moles can be a bad thing, as they tend to prevent beach migration - the sheltered beach 'disapears' over time)
4. A spy concealed withing an organisation, or group; this particular meaning was also the name of a (reality?) TV show which I presume was popular a while back. (~2000)
5. A lovely dark, pixel blemish, occaisionally hairy, and occaisionally a sign of impending cancer (When moles go bad!). Some people love 'em, some people hate 'em, it entirely depends where they are.
6. A unit of mesurement in chemistry. Probably originally short for molecule, it's abbreviated anyways to mol. I'm pretty sure it represents 6.022 x 10^23 atoms, or some such, so there is actually a 'mole day' on October 23, starting at 6:22 AM and going until 6:22 PM. Some chemical companies have moles as mascots, and some members of chemical companies don't like this. Guess they don't like moles...
7. Pronounced differently, this is a sauce... I think it involves avacadoes...
8. Molar pregnancy. Rather nasty. I'm pretty sure there's one in Like Water for Chocolate, the book. (Don't know about the movie) Combine definition 4 and 5, and that's what this baby is. With ultrasound, fewer of these go around for too long.

I think I'm actually out of definitions... there are, of course, still naked mole rats (which aren't true moles) mole men (subturanian race of humans which make me SO happy!) and numerous other sutto-moles still out there, but none of them landed in the dictionary. Then, of course, there is the mysterious Desmon, whose relationship TO moles I haven't a clue, but it keeps getting lumped in with them. In case anyone is curious, I am, in fact, also fond of desmons.
