I heard that making big life changes can sometimes be irreversible.

That's true, especially when it comes to moving to a new city or changing jobs.

Yeah, you really have to think things through since the effects can be irreversible.

Exactly, sometimes you just can't go back to how things were.

Root Explanation

Irreversible → It is formed from "in-" (meaning not) and "reversibilis" (from Latin, meaning able to be turned back). The word "irreversible" means not able to be turned back or changed.

Memory Tip

Think of 'not' ('in-') being able to 'turn back' ('reversibilis') — that's why irreversible means something that cannot be changed back.
