What does “irregardless” mean?

“Irregardless” is often mistakenly used to mean regardless. However, “irregardless” is not considered a real word by most dictionaries, and it should be avoided in formal or academic writing.

“Irregardless” is seen as incorrect because it adds the prefix “ir-,” which usually expresses negation, but actually means the same thing as regardless, not the opposite. While you may hear people say “irregardless,” it’s almost never encountered in published writing.
