Irregardless is a word, but it's not a proper word, and your student's assertion that it's in some dictionaries is a great opportunity to talk about the different kinds of dictionaries and the different kinds of entries in dictionaries. Irregardless Versus Regardless. First, let's talk about irregardless. Some people mistakenly use irregardless when they mean âregardless.â Regardless means âregard less,â âwithout regard,â or despite something. For example, Squiggly will eat chocolate regardless of the consequences. The prefix ir- (i-r) is a negative prefix, so if you add the prefix ir to a word that's already negative like regardless, you're making a double-negative word that literally means âwithout without regard.â.
