Root Explanation

Irrationally → It is formed from "ir-" (meaning not) and "rationalis" (from Latin, meaning reasonable or logical) and the suffix "-ly" (meaning in a manner). The word "irrationally" means in a manner that is not reasonable or logical.

Memory Tip

Think of 'not' ('ir-') being combined with 'reasonable' ('rationalis') to remember that 'irrationally' means acting in a way that lacks reason.
