From Ancient Greek κατα- (kata-, “down”) and ὁδός (hodós, “journey, way”), equivalent to AFrom Ancient Greek κατα- (kata-, “down”) and ὁδός (hodós, “journey, way”), equivalent to Ancient Greek κάθοδος (káthodos, “way down, descent”). Coined by English polymath William Whewell in 1834 for Michael Faraday, who introduced it later that year. By surface analysis, cath- (alternative form of cata-) + -ode.
