n
1: a conductor used to make electrical contact with some part of a circuit

Merriam Webster's

noun Date: 1834 1. a conductor used to establish electrical contact with a nonmetallic part of a circuit 2. an element in a semiconductor device (as a transistor) that emits or collects electrons or holes or controls their movements

Britannica Concise

Electric conductor, usually metal, used as one of two terminals to conduct electric current through a conducting medium. A simple voltaic cell, or battery, consists of two electrodes, usually one zinc and one copper, immersed in an electrolytic solution (see electrolyte). When a chemical reaction occurs in the solution, electrons gather on the zinc electrode, or cathode, which becomes negatively charged. At the same time, electrons are drawn from the copper electrode, the anode, giving it a positive charge. The difference in charge sets up a potential difference, or voltage, between the two electrodes. When they are connected by a conducting wire, electrons flow from the cathode to the anode, producing a current.

Oxford Reference Dictionary

n. a conductor through which electricity enters or leaves an electrolyte, gas, vacuum, etc. Etymology: ELECTRIC + Gk hodos way

Webster's 1913 Dictionary

Electrode E*lec"trode, n. [Electro- + Gr. ? way, path: cf. F. ['e]lectrode.] (Elec.) The path by which electricity is conveyed into or from a solution or other conducting medium; esp., the ends of the wires or conductors, leading from source of electricity, and terminating in the medium traversed by the current.

Collin's Cobuild Dictionary

(electrodes) An electrode is a small piece of metal or other substance that is used to take an electric current to or from a source of power, a piece of equipment, or a living body. The patient's brain activity is monitored via electrodes taped to the skull. N-COUNT
