## Definition

a small, round object that you put in a fireplace to control the flow of air and heat. It helps you keep the fire going without making the room too hot.

For teachers: a device used to regulate the flow of air into a fireplace or stove, typically consisting of a metal plate with a hole in the center. It functions as a heat regulator by controlling the amount of oxygen available to the fire.

## Examples

- He adjusted the damper to keep the fire burning.
- The cold draft in the living room was caused by a broken damper that allowed too much air to escape through the chimney.
- By partially closing the damper, the homeowner managed to maintain a steady, low-burning fire that provided warmth without consuming the entire supply of firewood in a single evening.
