erupt

erupt: [17] Etymologically, erupt means simply ‘break out’. It comes from the past participle of Latin ērumpere, a compound verb formed from the prefix ex- ‘out, from’ and rumpere ‘break’ (source of English rout, route, routine, and rupture, and related to bereave, rob, and robe). English actually acquired the derived noun eruption [15] before the verb.
=> bereave, corrupt, disrupt, rob, rout, route, routine, rupture
