Root Explanation

Irreversibly → It is formed from "ir-" (meaning not), "reversus" (from Latin, meaning turned back), and "-ible" (meaning capable of). The word describes a state that is not capable of being turned back or reverted.

Memory Tip

Think of something that cannot be 'turned back' ('reversus') — the 'ir-' means not, and '-ible' means capable. This helps you remember that 'irreversibly' means something that cannot be undone.
