Definition

To break out means to suddenly start or appear, especially something unwanted like a fire, fight, or disease.

When something breaks out, it begins suddenly and often spreads quickly. We commonly use it for events like a fire, a fight, war, or an illness. It can also mean to escape from a place such as a prison. The meaning depends on the context.

Examples

  • A fire broke out in the kitchen while I was making dinner.
  • A fight broke out near your seat during the concert.
  • War broke out before he could return home.
  • She broke out in a cold sweat when the alarm sounded.

Common mistake

Learners often confuse "break out" (start suddenly) with "break up" (end a relationship or separate).
