Irregardless isn't a word
Irregardless is a word commonly used in place of regardless or irrespective, which has caused controversy since the early twentieth century, though the word appeared in print as early as 1795. Most dictionaries list it as "nonstandard" or "incorrect" usage, and recommend that "regardless" should be used instead.
Sure it is! It means "without no regard."You go to school in England or some place?- oldman
