Root Explanation

Impair is formed from "in-" (meaning not) and "parare" (meaning to prepare or make equal). The word describes the act of making something not equal or reducing its quality or effectiveness.

Memory Tip

Think of something that is 'not' ('in-') 'equal' or 'prepared' ('parare') — that's why impair means to reduce quality or effectiveness.
