"nonstandard" - means people use it, but it's not "good english."

You'll find swear words in there, too... doesn't mean you should use them.

Irregardless bugs me because it ends up being a double negative, so it should logically mean regardful. Irr consistently means "not," as opposed to "in," which sometimes means "not," but can also mean "in" or the same thing as "en"... which is why "inflammable" isn't really such a double negative. Those things are able to be inflamed. However, flammable would more obviously connect with flames as opposed to athlete's foot

It *is* harder to communicate clearly with people when the consistent, standard patterns of our language have been eroded by disuse. However, it is in too many folks' best interest (as in financial) to be able to sell us ideas and products via verbal appeals to our emotions, and thus, analytical thinking has gone out of fashion. Our current educational system doesn't encourage it, either.
