Quick Answer
For standard English, regardless is the only correct choice. It means “despite everything” or “without paying attention to.”
Regardless
Irregardless
Note: While irregardless appears in some dictionaries as nonstandard, it is widely considered an error in professional and academic writing.
When you want to say that something will happen despite the circumstances, the word you need is regardless. It functions as an adverb meaning “without regard” or “unmindful.” Many speakers accidentally use the nonstandard form irregardless, likely confusing it with synonymous words like irrespective. To maintain credibility in your writing, always stick to the shorter, standard form.

Correct Usage of Regardless
The word regardless is primarily used as an adverb. It indicates that an action or situation will proceed despite potential obstacles, objections, or prevailing conditions. You will most often see it followed by the preposition “of” to form the phrase “regardless of.”
It is distinct from “regards” (which relates to greetings or attention). When you use regardless, you are essentially saying “without regard to X.” Source-1✅
Examples in Context
- We will continue the hike regardless of the weather.
- He decided to buy the car, regardless of the high cost.
- As a standalone adverb: The rain was pouring, but we carried on regardless.
Why “Irregardless” is Incorrect
The term irregardless is one of the most debated words in the English language. Linguistically, it is a double negative. The prefix ir- (meaning “not”) and the suffix -less (meaning “without”) cancel each other out, logically creating a meaning like “not without regard,” which is the opposite of what the speaker intends. Source-2✅
Most linguists agree that irregardless is a “blend word” (or portmanteau) resulting from the accidental confusion of two different standard words:
- Irrespective (meaning “not taking into account”)
- Regardless (meaning “without regard”)
While you may hear it in casual conversation, using it in professional emails, essays, or business documents can make your writing appear uneducated or careless.

Frequently Asked Questions
Is “irregardless” actually a real word?
Technically, yes, because it appears in many major dictionaries like Merriam-Webster and Oxford. However, it is labeled as nonstandard or informal. It acts as a synonym for regardless, but using it is widely considered a sign of poor grammar usage.
Can I use “regardless” at the beginning of a sentence?
Yes, absolutely. It is often used as a transition word to dismiss previous arguments or details. For example: “It might be expensive. Regardless, we need to purchase it immediately.”
What is the difference between “regardless” and “irrespective”?
They are nearly identical in meaning and are often interchangeable. Irrespective is generally considered slightly more formal. Also, “irrespective” must almost always be followed by “of” (irrespective of), whereas “regardless” can stand alone at the end of a sentence.
Is “regards” the same as “regardless”?
