The Origin of Regardless vs Irregardless

Understanding the history of these words makes the difference easier to remember.

Origin of Regardless

The word regardless dates back to the 1500s. It combines:

• Regard = attention or concern
• Less = without

Together, regardless literally means:

Without paying attention to something.

Example:

✅ She continued regardless of criticism.

Over time, the word became widely accepted in both British and American English.

Origin of Irregardless

The word irregardless appeared much later, around the late 1700s.

Language experts believe it developed when speakers blended words such as:

• Regardless
• Irrespective

Because many English words begin with the prefix ir-, some speakers naturally added it to regardless, creating irregardless.

Why the Spelling Difference Exists

The prefix ir- often means “not.”

Examples include:

• Irregular
• Irrelevant
• Irresponsible

Because regardless already contains the suffix -less, some grammar experts view irregardless as unnecessary or redundant.

Despite this criticism, the word continues to appear in spoken English and informal communication.
