anode (n.)

1834, coined from Greek anodos "way upward," from ano "upward," from ana "up" (see ana-) + hodos "a way," a word of uncertain origin. Proposed by the Rev. William Whewell (1794-1866), English polymath, and published by English chemist and physicist Michael Faraday (1791-1867). So called from the path the electrical current was thought to take. Compare cathode. Related: Anodic, anodal.
