an⋅ode

[an-ohd]
–noun
1. the electrode or terminal by which current enters an electrolytic cell, voltaic cell, battery, etc.
2. the negative terminal of a voltaic cell or battery.
3. the positive terminal, electrode, or element of an electron tube or electrolytic cell.

Origin:
1825–35; < Gk ánodos way up, equiv. to an- an- 3 + hodós way, road
an·ode   (ān'ōd')   
n.  
  1. A positively charged electrode, as of an electrolytic cell, storage battery, or electron tube.
  2. The negatively charged terminal of a primary cell or of a storage battery that is supplying current.

[Greek anodos, a way up : ana-, ana- + hodos, way.]
a·nod'ic (ə-nŏd'ĭk), a·nod'al (ə-nōd'l) adj., a·nod'i·cal·ly, a·nod'al·ly adv.

Anode

An"ode\, n. [Gr. ? up + ? way.] (Elec.) The positive pole of an electric battery, or more strictly the electrode by which the current enters the electrolyte on its way to the other pole; -- opposed to cathode.

anode 
1834, coined from Gk. anodos "way up," from ana "up" + hodos "way" (see cede). Proposed by Whewell and published by Eng. chemist and physicist Michael Faraday (1791-1867). So called from the path the electrical current was thought to take.

Main Entry: an·ode
Pronunciation: 'an-"Od
Function: noun
1 : the electrode of an electrochemical cell at which oxidation occurs: as a : the positive terminal of an electrolytic cell b : the negative terminal of a storage battery that is delivering current
2 : the electron-collectingelectrode of an electron tube —compare CATHODE
anode   (ān'ōd')  Pronunciation Key 
  1. The positive electrode in an electrolytic cell, toward which negatively charged particles are attracted. The anode has a positive charge because it is connected to the positively charged end of an external power supply.
  2. The positively charged element of an electrical device, such as a vacuum tube or a diode, to which electrons are attracted.
  3. The negative electrode of a voltaic cell, such as a battery. The anode gets its negative charge from the chemical reaction that happens inside the battery, not from an external source. Compare cathode.
