detonate: [18] Detonate is related to thunder. It comes from the past participle of Latin dētonāre, a compound verb formed from the prefix dē- ‘down’ and tonāre ‘thunder, roar’, which goes back to the same Indo-European base (*ten-, *ton-) as thunder. Latin dētonāre never actually meant ‘cause to explode’, though; that sense comes from its French descendant détoner.
