Morphology

electrode = electro + ode

Although the word is a scientific coinage built with electro- plus a Greek-derived second element, its meaning is not readily predictable for an average B1 learner.

Etymology

The word electrode comes from Greek parts electr- meaning 'amber', the old word people used for electricity, and -ode meaning 'way' or 'path', the same root as in electric and electron. So an electrode is like an 'electric path', the place where electricity goes into or out of something, which is why electrodes are used to connect devices or to measure electrical signals.
