wire

A wire is fundamentally a thin, usually round strand of metal, most commonly copper, but also aluminum, steel, or other materials. Its main job is to carry electricity or signals. You see wires everywhere: powering appliances, linking devices, and helping many everyday systems work. They're the hidden paths that make modern life possible.

But "wire" isn't limited to physical strands. It is also a verb with several meanings. To wire something can mean to connect it with electrical lines or circuitry, as in "The electrician wired the new outlet." It can also mean to equip a person or place with listening or recording devices. A detective might wire a suspect's office to gather evidence. In older use, people also wired money or wired news stories, meaning they sent them by telegraph. That older sense is the reason for the term "wire service" for news organizations such as the Associated Press.

Beyond electricity and espionage, "wire" also appears in names for things made from this material or shaped like it, such as a wire fence or a wire hanger. It has a figurative side too: if someone says they feel "wired," they usually mean they feel tense, excited, or too alert to relax, often as if they have had too much caffeine. Whether it carries power, sends news, helps with secret recordings, or describes a state of mind, this small everyday thing plays a surprisingly big role in our world.
