Root Explanation

Blackout → It is formed from "black" (from Old English "blæc", meaning dark or the color black) and "out" (meaning to extinguish or remove). The word "blackout" refers to the act of extinguishing light or visibility, resulting in darkness.

Memory Tip

Think of the color 'black' representing darkness and 'out' meaning to extinguish — together, they help you remember that a blackout means a complete loss of light.
