My point is that they are both considered largely incorrect and yet are used consistently by even educated persons.Damo, your example is a word that was created which did not exist, and etymologically, means the exact opposite of what it is used to express! This is not the case with the word "nuclear" at all. There are many examples of 'metathesis' in pronunciation of words, but 'irregardless' is not one of them. You are comparing apples to oranges... or an invented made up word, with a pronunciation of a word that already exists. In your example, the dictionary clearly points out it is erroneous and incorrect, in my example, it does not say it is incorrect pronunciation, just that many disapprove of the alternate pronunciation. The phrase "generally considered incorrect" is not the same thing as "it IS incorrect" one means one thing, the other means something else. There is no comparison between a word that is incorrectly using a double-negative in the suffix and prefix, and an alternative pronunciation of a legitimate word. Irregardless, is an ERRONEOUS word... (nōō'kyə-lər) is an alternate pronunciation of a legitimate word.
I know you are a bull head, and have to make yourself right, regardless... of the facts, so you go right ahead doing that, but you haven't proven your point, and you can't prove your point, because it is irrelevant!
They are much alike, even if you don't want them to be. One but has to look at the word to understand that it isn't spelled nucular, and that they are simply mistakenly pronouncing it like molecular without regard to the errancy. Just as anybody with understanding of the nature of words can see the irregardless is a redundancy.
