Let's start a grammar war!
It's Word Wednesday! The origin of "irregardless" is unknown. Many linguists think it is a blend of the words "irrespective" and "regardless." This is known as a portmanteau. Yet the blend presents a problem because of the two morphemes within it. The prefix ir- means "not" and the suffix -less means "without," creating a double negative within "irregardless." By this token, "irregardless" would mean "in regard to," which is not what proponents of the word say it means. What say you?
