Etymology

Origin of electricity

First recorded in 1640–50; electric + -ity

Explanation

Electricity is the energy that powers your lights and appliances. Electricity is the stuff that Benjamin Franklin harnessed from lightning using a key and a kite. Don't try that on your own. The word electricity comes from the Greek electron, which doesn’t mean what you might expect. It means "amber," that yellow or reddish brown stone used for jewelry. The ancients noticed that when you rub amber, it gets an electrostatic charge and will pick up light things like feathers and straw. You can also describe other kinds of energy as electricity — when you're really crazy about someone, you can say there's electricity between the two of you.
