If you have ever stopped before writing “irregardless” or “regardless,” you are not alone. Many people search for “irregardless or regardless” because the two words look and sound very similar. Yet they do not have the same place in standard English.
The main confusion comes from everyday speech. Some people say “irregardless” and mean “regardless.” Others see it as a mistake because the word seems to contain two negative parts: ir- and -less.
This can make writers wonder which word is correct in an email, school paper, article, or business message.
The quick answer is simple: regardless is the standard and safest choice. Irregardless is a real word in some dictionaries, but it is often labeled nonstandard. It may sound natural in casual speech, but many readers still see it as incorrect.
This guide explains the difference, the history of both words, common mistakes, spelling rules, real-life examples, and which form you should use for your audience.
Irregardless or Regardless Quick Answer
Use “regardless” in standard English.
Regardless means:
- Despite something
- Without being affected by something
- No matter what happens
Examples
- Regardless of the weather, we will travel.
- She finished the project regardless of the cost.
- Regardless of what others think, he made his choice.
Irregardless is often used with the same meaning. However, it is widely seen as nonstandard.
Comparison Table: Irregardless vs Regardless
| Word | Meaning | Standard English? | Best Use |
| Regardless | Despite; no matter what | Yes | School, work, news, formal writing |
| Irregardless | Used to mean “regardless” | Often nonstandard | Casual speech only, if at all |
Professional advice: When you are unsure, always choose regardless.
The Origin of Irregardless or Regardless
The word regardless comes from the idea of acting without regard for something. In simple terms, it means not letting a fact, problem, or condition change your action.
For example:
Regardless of the rain, the game continued.
Here, the rain does not change what happens.
The word irregardless appeared later in American speech. It likely developed as a blend of words such as irrespective and regardless.
Because both words carry a similar idea, speakers may have combined them.
This is one reason spelling and usage differences can develop. Languages change through speech. People hear similar words, mix patterns, and create new forms.
The prefix ir- can suggest “not” in some English words, such as:
- Irregular
- Irresponsible
- Irrelevant
The ending -less can also suggest “without,” as in:
- Careless
- Fearless
- Endless
Because of this, some people think irregardless is a double negative. However, its history and modern use are more complex. The main issue is not simply grammar. The bigger issue is standard usage.
Today, regardless remains the accepted choice in formal and professional English.
British English vs American English Spelling
The question “irregardless or regardless” is mainly about word choice, not a major spelling difference between British and American English.

Less suitable:
Irregardless of the results, we will continue.
Better:
