Etymology

Origin of device

First recorded in 1375–1425; blend of late Middle English devis “discourse, division” and devise “heraldic device, will,” both from Anglo-French, Old French, from Latin dīvīsa, feminine of dīvīsus “divided, separated”; see divisible

Explanation

A device is really anything that has a specific use. It might be a tool or object, or a plan that is devised to accomplish something. If it has a purpose, it is a device. A device is a noun that can be used to describe anything, simple or complex, that is used for a specific purpose. You might have one device for opening bottles, and another for opening cans. You probably even have a device for turning on your TV. While these have specific names (bottle opener, can opener, remote), you can cover each with the generic term device. We can see its root in the Old French word devis, which meant “purpose” or “contrivance.”
