katodiseen

Katodinen is a Finnish adjective meaning related to the cathode, the electrode at which reduction occurs in an electrochemical cell or the negative electrode in many devices. The corresponding noun is katodi (cathode). Katodinen is used to describe properties, processes, or phenomena associated with the cathode, such as katodinen reaktio, katodinen potentiaali or katodinen sähkökenttä. In English scientific terminology the equivalent term is cathodic.

The word is derived from the Greek kathodos, meaning “the way down,” through Latin and Swedish influence, and it has become standard in Finnish science and engineering texts. The primary meaning remains tied to the cathode in electrochemistry, electronics, and related fields, but it also appears in contexts such as radiation physics when describing cathode-related phenomena.

The form katodiseen is an inflected form of the adjective used in cases that express direction or location relative to the cathode, for example katodiseen päin meaning “toward the cathode” or “in the direction of the cathode.” In Finnish, katode-related terms are common in scientific writing, and the base noun katodi alongside katodinen forms appears in discussions of electrochemical cells, vacuum tubes, and cathode-ray terminology.
