In electrology, the electrode toward which positively charged particles move in an electrolytic cell; the cathode.
From cate- (variation of cata-, meaning 'down' from Greek kata) plus electrode. The prefix originally indicated the direction of current flow in early electrical terminology.
This word is almost never used anymore because scientists standardized on 'cathode,' but studying obsolete electrical terms reveals how scientists have repeatedly redesigned nomenclature to be more logical and consistent.
