What Are Some Words That Start with the Prefix “Irr”?

In the English language, prefixes are an important part of word formation. One common prefix is “irr-“, which often conveys a sense of negation or opposition. Understanding this prefix can help you better grasp the meaning of a variety of words. But what exactly does “irr-“ mean, and what are some words that begin with it?

Let’s explore the prefix “irr-“ and some common words that use it.

What Does the Prefix “Irr-” Mean?

The prefix “irr-“ comes from the Latin “in-“ or “ir-“, both of which indicate a negation or reversal of meaning. When added to a word, it often means not or without, signaling the opposite of what the root word normally conveys. In simpler terms, “irr-“ turns a word into its negation, implying the absence or opposite of something.

For example:

• Irritable means someone who is easily annoyed or prone to irritation, the opposite of being calm or patient.
• Irrational refers to something that is not based on reason or logic, the opposite of being rational.
