A thin piece of metal that you can bend is a wire. Wire is used for carrying phone signals and electricity, and also to make Slinky toys and abstract sculptures. If you wear braces, you might even have wire in your mouth.
Most wire is a tubular strand of metal, like the wire in jewelry or in the fence around your chicken coop. There's also braided wire coated in protective plastic to make cables for connecting electronic equipment or transmitting signals. In the old days, you might've sent a wire, or telegram, to a friend. And if you wear a wire, that's a secret recording device. As a verb, wire originally meant "adorn with gold wire." Today it means "install wires" like when you wire a new house for electricity.
