Ok folks, at the risk of sounding like a big PIA, preachy, obnoxious grammar snob, I have to tell you once and for all; irregardless is not a word.
Now, in all fairness, according to American dictionaries, it is a word, but just because the Americans say it’s a word, doesn’t make it so. If you look in the Canadian Oxford Dictionary, you won’t find it at all, because, well, our English is better than theirs. There, I said it.
The Merriam-Webster’s Concise Dictionary of English Usage (which is American) explains that although it is commonly used in modern-day English, it is a double-negative and, therefore, not grammatically correct. AHA! Let me explain…(I’ll be brief, I promise)
“Ir” is negative; “re” is negative and, therefore, “Irre” is a double-negative, so it’s almost like saying “in regards to not regarding” which doesn’t even make sense. And is probably the opposite of what you’re trying to say. What you most likely mean is, regardless. Or, irrespective. These are two separate words that seem to have, over time, been blended together. They basically mean the same thing and are both correct, so please stop blending them. Every time you do, a puppy dies.
Save the puppies; stop saying irregardless. Please.
