Root Explanation

Energy → It is derived from the Greek word "energeia" (meaning activity or operation), which is formed from "en-" (meaning in) and "ergon" (meaning work). The word "energy" refers to the capacity to perform work or the active force that enables work to be done.

Memory Tip

Think of 'work' ('ergon') being done 'in' ('en-') a certain way — that's how you remember that energy is the capacity to do work.
