Unnumbered source etymology

Original entry ↗
noun

An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows inwards (and thus, electrons flow outwards). It can have either a positive or a negative voltage with respect to cathode of the same polarized device (depending on whether the device is a load or a source, respectively). · (by extension) The electrode at which chemical oxidation of anions takes place, usually resulting in the erosion of metal from the electrode. · The electrode which collects electrons emitted by the cathode in a vacuum tube or gas-filled tube. · That electrode of a semiconductor device which is connected to the p-type material of a p-n junction.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
