dynamo

A dynamo creates energy. It’s short for "dynamoelectric machine," which is a generator that cranks out electric currents. If someone calls you a dynamo, don’t get mad, it just means you’re energetic.

The word dynamo comes from the Greek dynamis for "power." Boom! It’s like dynamite! The inventor of the dynamo-electric machine knew that when he named the device that turns mechanical power into electric current. Dynamos have been used to make power since the 1800’s. Since dynamo is such a snappy name, it’s often used to describe high-energy people, too. Is your room a disaster? Call an organizing dynamo to help you clean it up.
