Okay, then here's my chance to be a word-egghead.

There's a word we can all use to describe this phenomena of "language constantly evolving over time to serve its users" and that words is -----

::::::::::::drumroll::::::::::::::::::;

"Colloquial". As in "alot" has a "colloquial meaning". Actually, I'm not totally sure if I used it right, but I know I really like this word because it fits its meaning which I have been searching to describe for so long. Don't you love when you find out there's a word for something you have been trying to say? I'll never forget when I discovered the word "pretentious".....sigh.
