Disregard the Irregardless

A student came up to me after class and asked if irregardless was a word.  This prompted GG’s latest mini-lesson:

Irregardless vs. Regardless

To answer my student’s question, irregardless is not a word.  It is a double negative, combining the words regardless and irrespective.  Yes, there can be double negatives in English as well as mathematics.  Let’s take a closer look:  Regardless means despite something or without regard.  If we say irregardless, we are literally saying without without regard.  This does not make sense!

Here’s an example of the correct usage of regardless:

Regardless of the obstacles, he persevered and overcame his hardships.

Regardless of the obstacles, he finished the race!
