Origin & History of “dynamic”

Greek dūnamis (a word of unknown origin) meant ‘strength’. It was used by the Swedish chemist Alfred Nobel in 1867 to form the name of the new explosive he had invented, dynamite. From it was derived the adjective dunamikós ‘powerful’, which French adopted in the 17th century as dynamique, and English acquired it in the early 19th century. Related to dúnamis was the verb dúnasthai ‘be strong’ or ‘be able’; from this was derived the noun dunasteíā ‘power, domination’, source, via French or late Latin, of English dynasty (15th c.). part of the same word family is dynamo (19th c.), short for dynamo-electric machine, a term coined in 1867 by the electrical engineer Werner Siemens.
