cathodenoun

Etymology: From κάθοδος.
Wikipedia
Cathode
A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes the direction in which positive charges move. Electrons have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow. Consequently, the mnemonic cathode current departs also means that electrons flow into the device's cathode from the external circuit. For example, the end of a household battery marked with a + (plus) is the cathode. The electrode through which conventional current flows the other way, into the device, is termed an anode.
Webster Dictionary
Cathodenoun
the part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode
Etymology: [Gr. descent; down + way.]

Cathode
A cathode is an electrode through which electric current flows out of a polarized electrical device. The direction of electric current is, by convention, opposite to the direction of electron flow. This convention is sometimes remembered using the mnemonic CCD for cathode current departs. Cathode polarity is not always negative. Although positively charged cations always move towards the cathode and negatively charged anions move away from it, cathode polarity depends on the device type, and can even vary according to the operating mode. In a device which consumes power, the cathode is negative, and in a device which provides power, the cathode is positive: ⁕In a discharging battery or a galvanic cell the cathode is the positive terminal since that is where the current flows out of the device. This outward current is carried internally by positive ions moving from the electrolyte to the positive cathode. It is continued externally by electrons moving inwards, negative charge moving one way constituting positive current flowing the other way. For example, the Daniell galvanic cell's copper electrode is the positive terminal and the cathode.
Chambers 20th Century Dictionary
Cathode
kath-ōd′, n. the negative pole or electrode of a galvanic battery, as opposed to anode: the surface in contact with the negative pole: the object to be coated in electroplating—adj. Cath′odal. [Gr. kathodos, a going down, kata, down, hodos, a way.]

Examples of cathode in a Sentence
The last best hope of earth, two trillion dollars in debt, is spinning out of control, and all we can do is stare at a flickering cathode-ray tube as Ollie answers questions on TV while the press, resolutely irrelevant as ever, asks politicians if they have committed adultery. From V-J Day 1945 to this has been, my fellow countrymen, a perfect nightmare.
