A type of ghost that is known for making loud noises and causing disturbances, often in a playful or mischievous way.
The old house was said to be haunted by a poltergeist that would knock over furniture at night.
Poltergeist is formed from "poltern" (from German, meaning to make noise or to rumble) and "geist" (from German, meaning spirit or ghost). The word describes a noisy spirit or ghost that is believed to cause disturbances.
Imagine a spirit that makes a lot of noise — 'poltern' means to make noise, and 'geist' means spirit. This helps you remember that a poltergeist is a noisy ghost.
