What Does “Irregardless” Mean?

The irregardless definition surprises many English learners because it means almost exactly the same thing as regardless.

The irregardless meaning is:

Despite everything or without considering something.

Although the meaning is nearly identical, its reputation is very different.

Most dictionaries label irregardless as:

• Often criticized

This means the word exists, but grammar experts generally advise against using it in professional communication.

Irregardless in a Sentence

These irregardless examples illustrate how the word is commonly used.

• Irregardless of the rain, they finished the match.
• She continued irregardless of everyone’s advice.
• He accepted the position irregardless of the criticism.

These sentences are understandable, but nearly every editor would replace irregardless with regardless.

Is Irregardless Really a Word?

One of the most common search queries is:

“Is irregardless a word?”

The answer is yes.

Many respected dictionaries include it because their purpose is to record words people actually use.

However, another common question is:

“Is irregardless correct?”

For formal English, the answer is generally no.

A word can exist in a dictionary while still being considered poor style in professional writing.

This distinction is important because dictionaries are descriptive, not always prescriptive.

• Descriptive grammar records how people actually speak.
• Prescriptive grammar recommends how people should write in standard English.

This is why dictionaries acknowledge irregardless, while teachers and editors usually discourage it.

Why Do Dictionaries Include “Irregardless”?

Many readers assume that if a word appears in a dictionary, it must be correct.

That isn’t always true.

Modern dictionaries document language usage, including slang, regional expressions, historical words, and controversial terms.

Because millions of English speakers have used irregardless for more than a century, dictionaries include it with a usage note explaining that it is nonstandard usage.

In other words:

• A dictionary entry does not automatically mean a word is recommended.
• It simply shows that enough people use the word for readers to encounter it.

This distinction explains why irregardless has a dictionary entry but still appears in many lists of common grammar mistakes.

The History of “Irregardless”

Understanding the history helps explain today’s debate.

Linguists believe irregardless first appeared in the United States during the early 1900s. It likely developed from everyday speech as people blended irrespective and regardless into a single word.

Over time, the word spread through casual conversation and regional dialects. Since so many people continued using it, dictionaries eventually documented it.

Even today, however, most grammar experts, copy editors, and professional writers recommend avoiding it because regardless already expresses the same meaning more clearly.

This debate is an excellent example of how the English language evolves over time while still maintaining standards for formal writing.

Why Is “Irregardless” Considered Nonstandard?

Many people believe irregardless sounds incorrect because it appears to contain a double negative.

Let’s break it down.

• ir- means “not.”
• -less also creates a negative meaning.

Because both elements suggest negation, the structure seems redundant.

Although linguists point out that language doesn’t always follow perfect logic, this unusual construction has led many teachers to discourage the word.

As a result, most style guides, editing tips, and proofreading tips recommend replacing irregardless with regardless whenever possible.

How to Pronounce Both Words

Correct pronunciation is another common search intent.

Regardless

Pronunciation: ri-GARD-less

IPA: /rɪˈɡɑːrdləs/

Irregardless

Pronunciation: ir-ri-GARD-less

IPA: /ˌɪr.rɪˈɡɑːrd.ləs/

Although they sound similar, you’ll hear regardless far more often in professional settings, news broadcasts, classrooms, and public speaking.
