a metal handshake between the wired world and everything that flows or fizzes.

means A conductor through which electric current enters or leaves something — a battery, a circuit, a flame, a body, a vat of chemistry.

from Coined in the 19th century by the English scientist Michael Faraday, working with classical scholar William Whewell, who built a whole vocabulary of electricity from Greek. 'Electrode' fuses 'elektron' — Greek for amber, the fossilized resin that crackled and drew bits of straw when rubbed, the ancient world's first brush with static charge — with 'hodos,' meaning 'way' or 'path.' So at its root an electrode is literally the 'amber-way': a road for electricity to travel. The same 'hodos' lives in 'anode' and 'cathode,' the up-path and down-path Faraday named alongside it.

Faraday coined it from Greek for 'electric way'
anode vs cathode
named by direction current flows, not charge
