erupt

A rash, a volcano, applause, violence, all of these are things that are prone to erupt, meaning they suddenly become active.

The word erupt has origins in the Latin word eruptus, the past participle of erumpere, meaning to burst forth. This lively verb can be used to describe anything that is released in a quick, violent burst, such as a bomb exploding or lava spewing forth from a volcano or even laughter. It can also be used to describe the arrival of things that burst through more quietly (but often more painfully), such as a skin condition or a tooth that’s breaking through one's gum.
