I have never heard a junior use the word irregardless

In 1990 (a very long time ago for you babies out there) I was working at a company calle Mobil. They do oil and natural gas exploration, refining, etc,etc. One of our section managers was forever sending reports back to one of my friends to be rewritten. One of his favourite words was irregadless. It wasn't about correct English though, it was about business speech.

At the time me and some of my friends from Uni were on a crusade to restore the lost English Language. We railed against words that didn't fit, wrote americanisms and other bastardisations of English down on bits of paper and burned them symbolically. And of course we would find at least one word a week to restore to its former glory. I think our favourite word was the verb Promenade. It's a very hard word to use though.

Queer as all that may be, we never had anything against the word 'irregardless'. Odd that. It feels English. So we left it alone.

And no, I don't remember too may of the other words. And it was all a long time ago and, in hidsight, pretty silly.

Anyway(s), I dont believe that the English world as we know it will fall into disarray because some people use words that may or may not have originated more than a score of generations ago. What is language anyway(s)?
