Morphology

cathodic = cathode (transparent) = cathode + ic

Formed by the regular adjective suffix '-ic' from the noun 'cathode', so the meaning 'relating to a cathode' is directly derived.

Etymology

Cathodic comes from Greek parts kata- 'down' and hodos 'way', so it originally meant a 'way down'. In electricity and chemistry a cathode is the place where certain reactions happen, so cathodic describes things that happen at that part, for example metal forming or protection from corrosion.
