Morphology

detonator = detonate (transparent) = detonate + or

The suffix '-or' clearly indicates an agent noun, meaning 'one who detonates'.

Etymology

Detonator comes from the old parts de- and tonare, where tonare means 'to thunder' and de- means 'down' or 'away'. A helpful image is a small thing that makes the big blast 'thunder', so a detonator is the device that starts or triggers an explosion.
