Is it ‘irregardless’ or ‘regardless’?

‘Irregardless’ is often used to mean regardless. However, ‘irregardless’ is considered a nonstandard word, and it should be avoided in formal or academic writing.

‘Irregardless’ is often 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.
