erupt

Think of a volcano - when it erupts, lava and ash burst out with great force. But "erupt" is not just for volcanoes. It can also describe something that suddenly starts or breaks out, like anger, laughter, applause, fighting, or a debate. If someone has been holding in strong feelings, they may suddenly erupt in anger. A rash or pimples can also erupt on the skin. The key idea is that something appears or begins suddenly, often with a lot of force.

To erupt means to suddenly burst forth with energy or violence. It's most commonly associated with volcanoes, where it describes the forceful expulsion of lava, ash, and gases from beneath the Earth's surface: "The volcano erupted after centuries of dormancy."

However, erupt isn't limited to geological events. It can also be used figuratively to describe a sudden outbreak or display of something, often strong emotion or conflict. "After years of silence, his anger finally erupted." This suggests that feeling had been building for a long time before suddenly bursting into the open.

You might also hear it used for the sudden appearance of something on the skin: "Pimples began to erupt on her forehead." It can also describe an event or reaction that starts very suddenly: "A heated debate erupted during the meeting." In the same way, laughter, applause, violence, protests, or panic can erupt when a situation changes fast.

The word carries a sense of power, force, and often unpredictability. While volcanoes are the clearest example, erupt can be used for many kinds of sudden release, from natural events to emotions, arguments, crowds, and skin problems. It often suggests that something was building beneath the surface and then came out all at once.
