Conversation

Have you ever met someone who is a total nonreactor?

Yeah, it's interesting how they just stay calm no matter what happens.

I think being a nonreactor can be really helpful in stressful situations.

Definitely! They seem to handle pressure better than most of us.

Root Explanation

Nonreactor → It is formed from "non-" (meaning not) and "reactor" (from Latin "reagere", meaning to act in response). The word "nonreactor" refers to something that does not act in response or does not react.

Memory Tip

Think of 'not' ('non-') reacting or responding ('reactor') — that's why a nonreactor means something that does not react.
