To begin; the Oxford dictionary has over 170,000 words plus almost 50,000 considered obsolete. The Mariam-Websters has 470,000. The average English vocabulary runs some 20-35,000 words. I'm betting Stephen King's vocabulary runs well over a hundred thousand. So what the Hell does that even amount to? To see, at least for me, I'm going to kick it around a little here.

There's more, there's always more but you get my drift here right? I think words cover every single one of the bases. Besides, what the Hell would we do without them? Just look at each other, make faces and expressively grunt? Well, maybe we could make a good argument for that too...
