Root Explanation

Impede is formed from "in-" (meaning not) and "pedere" (meaning to foot or to walk). The word describes the act of preventing or obstructing movement, as if one is not able to walk freely.

Memory Tip

Think of being unable to 'walk' ('pedere') because something is 'not' ('in-') allowing you to move. This helps you remember that 'impede' means to obstruct or hinder movement.
