means Thin, flexible strands of metal drawn out into long threads, used to carry electrical current, signals, or to bind and support things.

from From Old English 'wīr,' meaning metal drawn into a thread, with cousins across the Germanic languages (Old Norse had 'vírr'). The deeper root is likely the same one behind Latin 'viere,' to plait or weave — fitting, since the earliest wire was literally drawn and twisted by hand. For most of its life the word meant the metal thread itself; only with the telegraph in the 19th century did 'the wire' come to mean the message, and later 'wired' came to mean nervy, connected, or quietly listened-in-upon.
