Etymology

Origin of cordless

First recorded in 1905–10; cord + -less

Explanation

A small electronic device or power tool that doesn't have a cord and a plug for an electrical outlet, but instead is powered by a battery, is cordless. A cordless tool or device requires power to work but doesn't use wall-outlet electricity. Drills, vacuum cleaners, hair dryers, and irons can all be cordless, often by using rechargeable batteries. Since cordless appliances don't need to be attached to an outlet, they are more mobile and handy. Telephones were first available in cordless versions in the 1980's — before that, the handset was always attached to a base by a cord.
