So exactly what is your problem regarding"irregardless"? To anyone who knows the English language reasonably well, that word makes no sense, and that is why it is not considered an actual word by most authorities. Do you think it should be considered a valid word, or what? If it were a valid word, then what would it mean?
I am asking why it continues to be used as a word for more than a century now. The question is: if it is being used so consistently, is it simply a mistake or is that mistake an example of an intrusive prefix that draws from old rules in the English language? And if that is the case, what is the rule and does it change the context of its usage over the correct word?
