cation

/ˈkæˌtaɪən/ noun C1

a positively charged ion

Word Origin Cation is a positively charged ion that moves toward the cathode (negative electrode) during electrolysis. From Greek kata- 'down' + ion 'going' (from ienai 'to go'). So cation literally means 'going down'. The kata- prefix appears in catalog (list down), catapult (throw down), catastrophe (turning down), and catatonic (stretched down). Ion itself is from the same root, meaning 'a goer', and anion is 'going up'. So cation is part of a family of 'going' words.
