irregardless (regardless)

People often say or write "irregardless," but it's nonstandard in formal English. For clear, professional sentences, replace it with "regardless" or another concise alternative - examples and ready-to-use rewrites follow.

Quick answer

Don't use "irregardless" in formal writing. Replace it with "regardless of," "despite," "in spite of," "no matter," or rephrase with "although"/"even though" for clauses.

"Irregardless" is nonstandard; "regardless" already conveys the negative sense.
Use "regardless of + noun phrase" or "despite/in spite of + noun phrase."
For full clauses, prefer "even though" or "although."

Core explanation (short): why "irregardless" is flagged

"Irregardless" tacks an extra negative-like prefix onto a word that already means "without regard." That redundancy makes it nonstandard in formal writing. Style guides and editing practice favor the simpler, standard forms.

'Regardless' = without regard; structure: "regardless of + noun phrase."
'Despite' or 'in spite of' work for similar prepositional uses.
Use 'although' or 'even though' when the following element is a clause.

Grammar note

The issue is one of redundancy rather than strict grammatical breakdown: "ir-" replicates the negation already embedded in "regardless." Some dictionaries list "irregardless" as dialectal or nonstandard, but most style guides advise avoiding it in edited prose.

Real usage and tone: when you might hear it (and what to do)

"Irregardless" appears in informal speech, interviews, and social posts. Preserve it when quoting someone verbatim for authenticity; otherwise, switch to a standard form for emails, reports, essays, and published copy.

Spoken or quoted material: acceptable to keep for fidelity; add a note if clarity matters.
Professional or academic writing: replace it.
Casual social posts: replace it unless the informal voice is intentional.

Quoted (preserve): "Irregardless of what they say, I'm sticking to my plan." - keep in a transcript.
Edited (change): "Regardless of what they say, she stuck to her plan." - use in published prose.

Hyphenation, spacing, and a quick memory trick

Write "regardless of" as two words. Don't hyphenate or split it unusually. The single-word "irregardless" is the nonstandard form to avoid in edited writing.

Correct: "regardless of" (two words).
Incorrect: "irregardless", "ir-regardless", "ir regardless", "regardless-of".
Memory trick: think "regard + less" - less regard = regardless. Drop the extra "ir."

Usage: Wrong: ir-regardless of the results.
Correct: regardless of the results.

Redundant negatives and invented prefixes crop up often. Fixing them clarifies your meaning.
