`WORD HISTORY: The same man who gave us dynamite gave us
`the Nobel Peace Prize, an irony that was surely not lost on the
`pacifistic Alfred Nobel himself. It is perhaps less well known that
`Nobel also contributed the word dynamite. Coined in Swedish in
`the form dynamit,
`the word was taken from Greek dunamis,
`“power,” and the Swedish suffix —it, which corresponds to our
`suffix —ite used in various scientific fields. Greek dunamis also
`gave us words such as dynamic and dynamo and itself probably
`goes back to the verb dunasthai, “to be able,” from which comes
`dynasty.
