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 the English 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 English dynasty.
