Irregardless or regardless? If you have ever stopped while writing an email, homework answer, or social media post because you were not sure which word to use, you are not alone.
hese two words look almost the same, and many people use them in speech. That can make the choice confusing, especially for English learners.
The good news is that the answer is simple: regardless is the standard word you should normally use. It means “despite something,” “without considering something,” or “it does not matter what happens.”
Irregardless is also used by some English speakers, and dictionaries record it as a word. However, it is widely considered nonstandard or informal, and many teachers, editors, and careful writers advise avoiding it.
This small difference matters because using the right word can make your English sound more natural and professional. You
may see irregardless in conversation, online posts, or casual speech, but regardless is the safer choice in school, business writing, exams, and formal communication.
By the end of this guide, you will know what both words mean, why irregardless causes confusion, how to use regardless correctly, and how to avoid common mistakes. You will also see simple examples from everyday English.
What Does “Irregardless” Mean?
Irregardless is used by some speakers to mean regardless.
In other words, when someone says:
“Irregardless of the weather, we will go.”
they normally mean:
“Regardless of the weather, we will go.”
The meaning is usually “despite,” “without considering,” or “no matter what.”
However, there is an important point for English learners: irregardless is not the preferred standard form. It is often labeled nonstandard or informal in dictionaries and usage guides. Some people strongly dislike it because they see it as an unnecessary combination of irrespective and regardless.
When is “irregardless” used?
You may hear or see irregardless in everyday conversation. Some native speakers use it naturally and may not realize that other speakers consider it incorrect or poor style.
For example:
- Irregardless of the cost, he wants to buy the car.
- Irregardless of what happens, I will support you.
- She decided to continue, irregardless of the problems.
- Irregardless of your opinion, the meeting will happen.
- They went outside, irregardless of the rain.
- Irregardless of the result, we learned something useful.
- He kept working, irregardless of how tired he was.
- Irregardless of the situation, stay calm.
These sentences are understandable, but in standard English, it is better to replace irregardless with regardless.
Why does “irregardless” sound strange to many people?
The main reason is its structure.
The prefix ir- often has a negative meaning. For example:
- regular → irregular
- responsible → irresponsible
- relevant → irrelevant
Because regardless already expresses the idea of “not considering” something, adding ir- can make the word seem unnecessary or confusing.
There is also a history of influence from words such as irrespective. Over time, irregardless became established in some speech communities.
So, while you may encounter it, you should not choose it when you want clear, standard English.
The easiest rule
If you are a student or English learner, remember this:
Use “regardless.” Avoid “irregardless,” especially in formal writing.
That one rule will keep your English safe in most situations.
What Does “Regardless” Mean?
Regardless is the standard and widely accepted word.
It means without considering something, despite something, or no matter what.
It is commonly followed by of when a noun, pronoun, or noun phrase comes after it.
The most common structure is:
regardless of + noun/pronoun
For example:
Regardless of the weather, we will play.
This means that the weather will not change our decision.
Here are more examples:
- Regardless of the cost, she wants the dress.
- We will continue regardless of the difficulties.
- Regardless of what he says, I trust you.
- You should be kind to people regardless of their background.
- I will finish the work regardless of how long it takes.
- Regardless of the result, you should be proud of yourself.
- He went to school regardless of his fear.
- Regardless of your decision, I will respect you.
When should you use “regardless”?
Use regardless when one fact does not change another action, decision, or result.
Consider this situation:
It is raining, but you still plan to go outside.
You can say:
Regardless of the rain, I am going outside.
The rain exists, but it does not change your plan.
You can also use regardless at the end of a sentence:
I am going to the party regardless.
Here, regardless means something like “anyway” or “despite that.”
For example:
“It might be expensive.”
“I want to go regardless.”
This means the possible high price will not change the speaker’s decision.
Common structures with “regardless”
There are several useful patterns.
1. Regardless of + noun
Regardless of the price, I will buy it.
2. Regardless of + pronoun
Regardless of what you think, I have made my decision.
3. Regardless of + -ing form
Regardless of being tired, she continued working.
4. Regardless of whether + clause
Regardless of whether he comes, we will start at eight.
5. Sentence + regardless
I will help you regardless.
These structures are useful in both spoken and written English.
Difference Between Irregardless and Regardless
The biggest difference is not really their basic meaning. Both are generally used to express the same idea.
The important difference is standard usage and acceptability.
| Feature | Regardless | Irregardless |
|---|---|---|
| Meaning | Despite something; no matter what | Usually the same meaning |
| Standard English | Yes | Generally considered nonstandard |
| Common in formal writing | Yes | Avoid |
| Common in casual speech | Yes | Sometimes |
| Good choice for exams | Yes | No |
| Good choice for business writing | Yes | No |
| Meaning is usually understood | Yes | Yes |
| Best choice for learners | Yes | No |
Usage difference
If you are writing an essay, application, report, email, or school assignment, choose regardless.
For example:
Regardless of the difficulties, the company continued its work.
This sounds natural and professional.
Using irregardless may attract unwanted attention from readers who consider it an error:
Irregardless of the difficulties, the company continued its work.
The meaning is clear, but the word choice is less acceptable in careful writing.
Grammar logic
Regardless is an established adverb and is commonly used in the phrase regardless of.
The word can introduce a condition or fact that does not affect the main statement.
For example:
Regardless of the weather, we will travel.
The main idea is:
We will travel.
The extra information is:
The weather does not matter.
Sentence structure
A very common structure is:
Regardless of + noun, main clause
Regardless of the price, I will buy it.
Another common structure is:
Regardless of + what/where/who/how/whether + clause
Regardless of what happens, remain calm.
Regardless of where you live, you can learn English.
Regardless of how difficult it seems, keep trying.
Notice that regardless of is normally followed by of before a noun or similar phrase.
Grammar Rules You Must Remember
Rule #1: Use “regardless” as the standard choice
When you need the word in normal English, choose regardless.
Correct:
Regardless of the weather, we will go.
Not recommended:
Irregardless of the weather, we will go.
For learners, there is no reason to choose the less accepted form.
Rule #2: Use “regardless of” before a noun
When a noun follows the expression, use regardless of.
Regardless of the cost, he bought the phone.
Regardless of the time, she continued studying.
Regardless of the problem, we must find a solution.
Do not remove of when a noun follows.
Rule #3: “Regardless” can be followed by a clause
You can use regardless of what, who, where, when, why, how, or whether.
Examples:
Regardless of what happens, stay calm.
Regardless of where you go, be careful.
Regardless of how difficult it is, keep practicing.
Regardless of whether she agrees, we will continue.
This pattern is especially common in everyday English.
Rule #4: “Regardless” can stand at the end
You do not always need of.
For example:
I am going regardless.
Irregardless or Regardless
Irregardless or Regardless
Here, regardless means anyway or despite that.
This is completely normal English.
Common Mistakes Students Make
Mistake 1: Choosing “irregardless” because it sounds stronger
Some learners think irregardless is a stronger version of regardless. It is not.
You do not need ir- to make the meaning stronger.
Incorrect idea:
Irregardless or Regardless
That is not how these words work.
Instead, simply use regardless.
Mistake 2: Forgetting “of”
A common mistake is:
Irregardless or Regardless
The standard structure is:
Irregardless or Regardless
Remember:
regardless + of + noun
Mistake 3: Using “regardless” when “regarding” is intended
This is a different problem.
Regardless means “despite” or “without considering.”
Regarding means “about” or “concerning.”
Compare:
Irregardless or Regardless
This means the problem did not stop us.
But:
Irregardless or Regardless
This means “about the problem.”
These two words are not interchangeable.
Mistake 4: Thinking “irregardless” is always completely meaningless
It is not accurate to say that nobody understands irregardless. Many English speakers use it, and dictionaries record its use.
The better advice is:
It exists, but it is widely criticized and is not the best choice for standard English.
That is a more useful explanation for learners.
Mistake 5: Using “irregardless” in formal writing
Even if people around you use irregardless, it is safer to avoid it in:
- school essays
- exams
- job applications
- business emails
- reports
- academic writing
- professional documents
Simply use regardless.
Easy Trick to Remember the Difference
Here is a simple classroom trick:
REGARDLESS = READY FOR EVERY SITUATION
Think of regardless as saying:
Irregardless or Regardless
Rain? It does not matter.
Money? It does not matter.
Difficulty? It does not matter.
Someone’s opinion? It does not matter to the decision.
So:
Irregardless or Regardless
Think:
Rain does not matter → regardless.
What about “irregardless”?

Irregardless or Regardless

This is especially helpful for students taking English exams.
You do not need to spend time wondering whether irregardless is technically found in dictionaries. If your goal is correct, natural, standard English, regardless is the simple answer.
