Root Explanation

Reaction → It is formed from "re-" (meaning again or back) and "agere" (meaning to act). The word describes the act of responding or acting back in response to something.

Memory Tip

Think of responding 'again' ('re-') to an 'action' ('agere') — that's why reaction means a response to an action.
