burst forth suddenly and violently, especially when describing a volcano releasing lava, or sudden anger or applause.
From Latin 'eruptus', past participle of 'erumpere': 'e-' (out) + 'rumpere' (to break). Literally means 'broken out.'
When Mount Vesuvius erupted in 79 AD, the Latin word 'eruptus' was used by Pliny the Younger to describe it, making this one of the oldest recorded uses of the term—and we still use the exact same word!
