Modern English
power

Long before power meant electricity, it described the simple, muscular fact of being able to do something. Latin speakers used potis for “powerful,” and its descendant *potēre—“to be able”—eventually traveled through French before arriving in English as power around 1300. That same family produced potent and potentate: one means power concentrated in a substance, the other power concentrated in a ruler. English then kept enlarging the suitcase: by the 1720s, power could mean the rate at which work is done, and by 1896 it could flow through wires. Even horsepower, coined in 1805 under James Watt’s influence, measures power with an animal that was actually less efficient than the official unit suggests—so every electric motor carries a small, historical horse inside it.
