to burn out
phrasal verbC

To extinguish a fire by letting it consume all fuel
  • 1The campfire burned out overnight.
  • 2We let the candle burn out completely.
When a fire uses up everything it can burn, like wood or paper, it slowly gets smaller and smaller. When there is nothing left for the fire to eat, it stops by itself. No water or help is needed; the fire ends because there is nothing left to burn.

Campfires often burn out overnight if you don't add more wood, so people check in the morning to see only ashes left where the fire was.
