Root Explanation

Pacemaker → It is formed from "pace" (from Latin "passus", meaning step) and "maker" (from Old English "macian", meaning to make). The word "pacemaker" refers to something that makes or sets the pace or rhythm, particularly in a biological context, such as the heart.

Memory Tip

Think of someone who 'makes' ('maker') the 'steps' ('pace') for others to follow — that's why a pacemaker sets the rhythm.
