First off it's only three periods for the ellipsis ...(if you want nit?) Not two not four, just three, no more...

Second I found you explination of a logical term, interesting and thoughtful, even if not apropos of English usage.

Slippery - slimy, slick, greasy. Slope - slant, tilt, pitch. Or standing on an precarious incline.

Using a term from one endevour and attempting to appy it to another, may create a illogical conclusion that the usage and definition in the second aplication is the same as the first.

I do appreciate the lesson! Thanks for the education on alternate meanings/usage. I shouldn't persue this any further, or is it farther? lol

By the way, you made me look and Slippery Slope isn't in my Oxford Universal either. Something tells me, the term has a limited specific application in logical disection, but for the rest of us, it just means, "If you take something home for a casino, you are likely to take many more things home from a casino!" Now who contends that collecting chips, swizzles, ashtrays, keno ticktes, coin cups, dice, or tiny soaps, has anything to do with logic?
