Root Explanation

Nightmare is formed from "night" (from Old English "niht", meaning the period of darkness) and "mare" (from Old English "mære", meaning a mythological demon or goblin that torments sleepers). The word "nightmare" refers to a frightening dream that occurs during the night, often associated with feelings of fear or anxiety.

Memory Tip

Think of the 'night' as the time when dreams happen, and the 'mare' as a creature that causes fear. This helps you remember that a nightmare is a scary dream that occurs at night.
