Have you ever thought about the irreversibility of some decisions we make?

Root Explanation

Irreversibility → It is formed from "in-" (meaning not), "reversus" (the past participle of "vertere", meaning to turn), and "-ibility" (meaning the quality of being). The word describes the quality of not being able to turn back or return to a previous state.

Memory Tip

Think of something that cannot be 'turned back' ('reversus') — 'in-' means not, and '-ibility' refers to the quality of that state.
