If Latin is as high-falootin a language as you can have, what’s the lowest? Slang, of course. Everybody disparages slang, and everybody uses it. I suppose we mainly differ in which slang words we use, and which we don’t.
I’m not going to say a whole lot about this subject except to say that some folks study the topic rather seriously (I suppose everything is a topic of serious study for somebody), and a dictionary of sang was just released, and it’s online! That means you can go read it!
And for a commentary, go here.
This thing has a lot of words that I didn’t even know were words. Browse around and you might notice that a lot of accepted words started out as slang, and maybe some words that you think are slang aren’t. Try looking up your name.
Sometimes I wonder how Mr. Green defined slang. I looked up “roger” and didn’t see a reference to it as a synonym for yes or agreement.
Anyway, I invite you to go waste some time looking up some words.
