Irregardless is now a recognized word in Webster's.

Kind of like using the word "due" incorrectly, in place of "because of." I believe some dictionaries now have that as one of the definitions because it has become so mainstream to use the word that way.

There's lots of examples of words that are grammatically incorrect but we use them so what can you do?

It's like the word park, people say 'I can't find a park' instead of 'a parking spot'.

Park is a verb (to park a car) and is a noun for a recreational zone.

But now it's also a parking spot.

I suppose it's only a matter of time before "literally" gets officially redefined.

Words change meaning, new words come into existence, and old meanings of words are sometimes forgotten. A few months ago I bought a used book from Amazon. It was a book I know I'd probably read only once and never revisit, and when that's the case I'll go for the cheapest copy I can find. This one was a paperback, printed at the time of the book's original publication, about seventy years ago.

"Terrible" and "horrible" almost always mean "exceedingly bad" nowadays. But they also have the meanings "inspiring terror" and "inspiring horror." Those meanings are almost archaic now but were much more commonly used back then.

Anyway, on the back cover, where the publisher puts a sales pitch to get people to buy a book, it said "This is a terrible novel!"

I'll reserve my web searches to the Oxford Dictionary from now on.

irregardless, i don't like it.

it seems like a lot of language innovations are triggered by morons. that's been
the case most of my life, anyway, a'ight?

i do like british slang, though. its a lot wittier. i especially like the rhymy stuff,
such as :

"Apples and pears" (stairs) ...
"Army and navy" (gravy) ...
"Basin of gravy" (baby) ...
"Bees and honey" (money) ...
"Borrow and beg" (egg) ...
"Bottle and stopper" (copper) ...
"Box of toys" (noise) ...
"Can't keep still" (treadmill)

i never use it

Can't say I know for sure, but irregardless sounds like it had a slightly different meaning at some point, but got mixed with regardless because the two were so similar.

Since regardless means without regard to a situation, irregardless would be a weird way to say with regard to that situation. But I feel like there's another use for it, like if the regard for a situation was unknown.

Either way, the word has no practicality.
