Irregardless and regardless look like a simple pair, but one of them is not standard English at all. People use “irregardless” every day, yet most dictionaries call it nonstandard and most teachers mark it wrong. The correct word is regardless. This simple guide will explain why, with easy examples, a memory trick, and a mini quiz.

What Is the Simple Difference?
The simple difference is this: regardless is the correct, standard word meaning “without regard to” or “in spite of everything”. Irregardless is a nonstandard word that some people use to mean the same thing, but it is a double negative — “ir-” (not) plus “-less” (without) — and careful writers and examiners do not accept it. So always use regardless.
Irregardless: The Nonstandard Word
Irregardless (pronounced “ir-ih-GAHRD-luhs”) is a word people created by mixing “irrespective” and “regardless”. It is listed in some dictionaries, but only as nonstandard or informal. In formal writing, exams, and job applications, it is considered a mistake.
- He went out irregardless of the rain. (Nonstandard — avoid this.)
- She will come irregardless of what they say. (Nonstandard — avoid this.)
- Many people say irregardless, but it is not correct English.
Regardless: The Correct Word
Regardless (pronounced “rih-GAHRD-luhs”) is an adverb meaning “in spite of everything” or “without considering the problems”. It is the standard word to use in every situation.
- He went out regardless of the rain.
- She will succeed regardless of the difficulties.
- We must finish the work regardless of the cost.
The Easy Trick to Remember
- “Irregardless” has two negatives — “ir-” means “not” and “-less” means “without”. Two negatives make it wrong, like saying “I do not have no money.”
- Drop the “ir-“ — if you remove the first two letters from “irregardless”, you get the correct word “regardless”.
- Use “irrespective” if you want the “ir-“ — “irrespective of the rain” is correct, because “irrespective” is a real word.
- Say it as a rhyme: “If you want to be right, drop the ir- and use regardless day and night.”
