The word "burst" refers to the sudden and forceful breaking, exploding, or opening of something. It often implies a release of energy, pressure, or emotion, and can be observed in both physical contexts (like a balloon popping) and more abstract contexts (like a burst of laughter or creativity).
The word "burst" comes from the Old English "berstan," which means to break or to burst open. Its roots can be traced back to Proto-Germanic *bresðan and is related to various forms in older languages signifying breaking or exploding.
