Etymology
Etymology Information

'cathode' originates from Greek, specifically the word 'kathodos', where 'kata-' meant 'down' and 'hodos' meant 'way'.

Historical Evolution

'cathode' changed from the Greek word 'kathodos' and was adopted into scientific English in the early 19th century as a term for one of the electrodes in electrical experiments.

Meaning Changes

Initially it meant 'a way down' or 'descent', but over time it evolved into its current technical meaning of 'an electrode (often the negative one) where current leaves or reduction occurs'.

Meanings by Part of Speech
