Etymology
Origin of generator
1640–50; < Latin generātor producer, equivalent to generā ( re ) ( see generate) + -tor -tor
Explanation
If your neighborhood loses power, it’s good to have your own generator so you can keep the lights on. A generator is machine that produces power. Generator can also mean someone who creates something. If you come up with lots of ideas, you are an idea generator. Not so helpful during a blackout unless you had the idea to get a portable generator. This kind of generator makes electricity out of some other type of power (like wind power) or fuel (like propane or gas). In Latin, generator means "begetter or producer," from generare, "to bring forth."
