| 释义 | device (once / 193 pages) n 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.” WORD FAMILYdevice: devices USAGE EXAMPLESSingapore's TeleRadio Engineering uses RF signals in its SkyDroner device to track and control drones and a video feed to confirm targets visually.
