Irregardless vs. Regardless: Which is Correct to Use?

The English language is filled with linguistic puzzles that often spark passionate debates among grammarians and casual speakers alike, particularly when it comes to words that convey concession or indifference. One of the most contentious examples is the use of terms like regardless, irregardless, notwithstanding, and nonetheless, which function as adverbs or prepositions to indicate that something will happen despite other factors. These words allow us to navigate complex logical transitions in our speech and writing, providing a way to acknowledge obstacles while emphasizing a primary point. Understanding the nuances between these terms is essential for anyone looking to refine their professional communication or academic writing style.

For decades, the word “irregardless” has served as a lightning rod for criticism, often labeled as a non-standard or even “fake” word by those who prefer traditional linguistic standards. However, its persistent use in various dialects and its inclusion in major dictionaries suggest a more complex story about how language evolves over time. Whether you are a student preparing for an exam, a professional drafting an important report, or a language enthusiast curious about etymology, mastering the distinction between these terms is vital. This guide explores the history, structure, and proper application of these words to ensure your writing remains clear, authoritative, and grammatically sound.

Comprehensive Definition of Terms

To understand the debate, we must first define the core term: regardless. In its most common usage, regardless is an adverb that means “without paying attention to the present situation” or “despite everything.” It functions as a way to dismiss potential objections or conditions that might otherwise prevent an action from occurring. For example, one might say, “The game will continue regardless of the rain.” In this context, the rain is an irrelevant factor to the continuation of the game.

The term irregardless is defined by most modern dictionaries, including Merriam-Webster and the Oxford English Dictionary, as having the exact same meaning as regardless. However, it is almost universally accompanied by a “non-standard” or “informal” label. This means that while the word exists and is understood, it is generally discouraged in formal settings, such as academic papers, business correspondence, or legal documents. The “ir-” prefix is considered redundant because the “-less” suffix already conveys the negative or privative meaning.

In linguistic terms, these words are often used as conjunctive adverbs or prepositions (when followed by “of”). Their primary function is to provide a logical bridge between two ideas, where the second idea is presented as being unaffected by the first. This rhetorical device is known as a concession, where the speaker acknowledges a counter-argument or a difficult circumstance but proceeds with their main point anyway.

The Etymology and History of the Debate

The word regardless entered the English language in the late 16th century, combining the root word “regard” (meaning attention or care) with the Germanic suffix “-less” (meaning without). It was a straightforward construction that filled a specific need in the language. For centuries, it remained the undisputed standard for expressing the concept of indifference to circumstances.

The emergence of irregardless is a more recent phenomenon, appearing in the early 20th century, specifically around 1912. Linguists believe it originated as a portmanteau or a blend of two existing words: irrespective and regardless. By combining the negative prefix “ir-” from irrespective with the word regardless, speakers created a double negative that, ironically, retained the original meaning of the single negative.

The controversy began almost as soon as the word appeared. Prescriptive grammarians—those who believe there are strict rules for how language “should” be used—quickly condemned it as a sign of ignorance or poor education. They argued that because “ir-” means “not” and “-less” means “without,” the word irregardless should technically mean “not without regard,” which would be the opposite of its intended meaning. Despite this logical criticism, the word gained popularity in American English and has persisted for over a hundred years.

Structural Breakdown and Morphology

To truly understand why irregardless is criticized, we need to look at its morphological structure. Morphology is the study of how words are formed. In English, we use prefixes and suffixes to change the meaning or grammatical category of a base word. When we look at the word regardless, the structure is logical and efficient.

Base Word: Regard (Noun/Verb meaning attention or care)
Suffix: -less (Adjective-forming suffix meaning “without”)
Result: Regardless (Adjective/Adverb meaning “without regard”)

When we look at irregardless, the structure becomes problematic for many linguists because it introduces a redundant element. The prefix “ir-” is an allomorph of “in-,” which is used to negate the word it precedes. This creates a linguistic redundancy that does not add new meaning but does add extra syllables.

Table 1: Morphological Comparison
Element Regardless Irregardless Irrespective
Prefix None ir- (not) ir- (not)
Root regard (attention) regard (attention) respective (relating to)
Suffix -less (without) -less (without) -ive (forming an adjective)
Logical Meaning Without regard Not without regard Not relating to
Intended Meaning Without regard Without regard Without regard

As seen in the table above, irregardless creates a double negative. In most formal logic, two negatives cancel each other out to create a positive. However, in language, specifically in non-standard dialects, double negatives are often used for emphasis rather than to reverse the meaning. This is why irregardless is understood by everyone, even if it is technically redundant.

The Proper Usage of Regardless

The word regardless is the standard, accepted form in all levels of English, from casual conversation to the highest forms of academic and legal writing. It can be used in several different ways within a sentence. The most common use is as an adverb at the end of a clause to indicate that the preceding information does not change the outcome.

Another common usage is as part of the prepositional phrase “regardless of.” In this construction, regardless is followed by a noun or a noun phrase. This allows the writer to specify exactly what is being ignored. For instance, “Regardless of the cost, we must finish the project.” Here, the cost is the specific factor being dismissed as irrelevant to the goal of finishing the project.

It is also important to note that regardless can function as an adjective, though this is less common in modern English. In older texts, you might see it used to describe a person who is heedless or careless. However, in 99% of contemporary usage, it serves to provide a concessive transition between ideas.

The Controversy Surrounding Irregardless

Why does the word irregardless cause so much anger? The debate touches on the very nature of what makes a word “real.” For a descriptivist linguist, a word is real if people use it and others understand it. Since irregardless has been used for over a century and is found in literature and speech, descriptivists argue it is a valid, albeit informal, part of the English lexicon.

On the other hand, prescriptivists argue that language should follow logical rules. They view irregardless as a mistake that has been repeated so often that people have become used to it. They argue that including it in dictionaries “validates” poor grammar and contributes to the decline of linguistic clarity. This tension is why you will see many dictionaries include the word but with a heavy warning that it is non-standard.

In professional environments, using irregardless can have social consequences. It is often used as a “shibboleth”—a way to judge a person’s level of education or attention to detail. Using the word in a job interview or a high-stakes presentation might lead the audience to perceive the speaker as less professional, even if their message is perfectly clear. Therefore, even if you believe the word is valid, it is usually safer to avoid it in formal contexts.

Comparative Analysis: Regardless vs. Irregardless

When deciding which word to use, it is helpful to see them side-by-side in various contexts. The following table illustrates how regardless functions as the standard choice across different types of sentences, while irregardless is relegated to the informal column.

Table 2: Standard vs. Non-Standard Usage
Context Standard (Regardless) Non-Standard (Irregardless) Verdict
Formal Business We will proceed regardless of the risk. We will proceed irregardless of the risk. Use Regardless
Academic Writing The data is valid regardless of the sample size. The data is valid irregardless of the sample size. Use Regardless
Legal Documents The contract is binding regardless of the date. The contract is binding irregardless of the date. Use Regardless
Casual Speech I’m going to the party regardless. I’m going to the party irregardless. Acceptable but discouraged

As the table demonstrates, regardless is always a safe and correct choice. There is no situation where regardless would be considered incorrect, whereas irregardless is almost always viewed with some level of skepticism or disapproval in professional circles.

Synonyms and Sophisticated Alternatives

If you find yourself using regardless too frequently in your writing, or if you want to avoid the irregardless trap altogether, there are several excellent synonyms available. Each of these carries a slightly different nuance and can be used to elevate the tone of your prose. Words like irrespective, notwithstanding, and nonetheless are powerful tools for any writer.

Irrespective is perhaps the closest synonym to regardless. It is almost always used with the preposition “of.” It sounds slightly more formal and is often used in legal or official contexts. For example, “Benefits are granted to all employees, irrespective of their length of service.”

Notwithstanding is a more sophisticated choice. It can function as a preposition, an adverb, or even a conjunction. When used as a preposition, it can come before or after its object: “Notwithstanding the obstacles, we succeeded” or “The obstacles notwithstanding, we succeeded.” It adds a level of gravitas to the sentence.

Usage Rules: Comprehensive Coverage

To ensure you are using these words correctly, follow these specific rules of thumb. These rules cover syntax, punctuation, and stylistic choices that will help you avoid common pitfalls in your writing.

Rule 1: The Redundancy Rule. Always remember that regardless already means “without regard.” Adding the prefix ir- (which means “not”) creates a double negative. In formal writing, always strip the “ir-” away. If you feel the need for more emphasis, consider using a different word like “entirely regardless” or “irrespective.”

Rule 2: The Prepositional Rule. When using regardless to introduce a specific condition, it must be followed by the preposition of. You cannot say “Regardless the weather”; you must say “Regardless of the weather.” This is a common error where the preposition is dropped, leading to a fragmented or awkward sentence structure.

Rule 3: Punctuation Matters. When regardless is used at the beginning of a sentence as an introductory phrase, it should be followed by a comma. For example: “Regardless of the cost, we will buy it.” When used as a conjunctive adverb between two independent clauses, it should be preceded by a semicolon and followed by a comma: “The path was dangerous; regardless, they decided to continue.”

Rule 4: Register and Audience. Consider your audience before choosing your words. In a text message to a friend, irregardless might go unnoticed. In a master’s thesis or a cover letter for a job, it could be a fatal error. Always default to regardless in any situation where you want to be taken seriously as a writer or professional.

Common Mistakes and Misconceptions

Beyond the irregardless debate, there are other common mistakes writers make when trying to express concession. One of the most frequent is the confusion between regardless and regretfully or regrettably. While they sound vaguely similar, they mean very different things.

Another common mistake is the “double preposition” error. Some writers mistakenly say “regardless as to whether” instead of the simpler and more correct “regardless of whether.” The phrase “as to” is often unnecessary filler that clutters the sentence without adding clarity.

Table 6: Common Errors and Corrections
Incorrect/Weak Phrase Correct/Strong Phrase Explanation
Regardless as to whether… Regardless of whether… “As to” is unnecessary wordiness.
Irregardless of the fact… Regardless of the fact… Removes the non-standard prefix.
He was regardless of his safety. He was heedless of his safety. “Heedless” is a better adjective for people.
Regardless, of the time… Regardless of the time… Incorrect comma placement.
I will go, irregardless. I will go regardless. Standard adverbial ending.

Advanced Topics: Dialect and Register

For advanced learners, it is interesting to look at irregardless through the lens of sociolinguistics. The word is often cited as an example of metanalysis or hypercorrection. Hypercorrection occurs when a speaker tries to sound more formal or “correct” by applying a rule where it doesn’t belong. In this case, speakers might feel that regardless sounds too simple, so they add the “ir-” prefix to make it sound more like other “intellectual” words like irrelevant or irreparable.

Furthermore, irregardless is sometimes used in specific American dialects as an intensive. In these contexts, the extra prefix serves to add emotional weight to the statement, much like how some people use “literally” to mean “figuratively but very intensely.” While this doesn’t make it “correct” in formal English, it explains why the word remains so popular despite the constant criticism from teachers and editors.

In the world of lexicography (dictionary making), the decision to include irregardless is often a matter of descriptive vs. prescriptive philosophy. Dictionaries like Merriam-Webster argue that their job is to record how the language is actually used, not to act as “grammar police.” By including the word, they aren’t saying it’s “good” English; they are simply acknowledging that it is a word used by millions of people to mean a specific thing.
