It makes a little spider-like sensation creep up my spine every time I hear the word. And there’s certain people I know are going to use it. One co-worker says it at least seven times a day and I can see it coming about a mile away. She’ll start by saying blah blah blah and then “It’s just not right, irregardless of what he says!”
Irregardless is not a word!
I suspect it is a home-made blend of irrespective and regardless, both of which are commonly accepted standard English words. By blending these words, an illogical word is created! Since the prefix ir- means ‘not’ (as it does with irrespective), and the suffix -less means ‘without,’ irregardless turns this slosh of letters into a double negative.
Cringe, cringe, cringe!
Another possibility is that when people say “irregardless” they are thinking of words like “irrelevant”, “irrational” and “irregular”.
It’s almost as bad as unthaw!
“Hey Hazel, would yer look in the ice box and see if there’s some hamblebooger to unthaw? I want a booger tonight, irregardless of what Dr. Oz sez.”
