cataract

From Middle English cataract, cateract, cateracte, cataracta, from Latin cataracta (“waterfall, portcullis”), from Ancient Greek καταρράκτης (katarrháktēs), from καταράσσω (katarássō, “I pour down”), from κατα- (kata-, “down”) + ἀράσσω (arássō, “to strike, dash”).[1][2] Its pathological sense probably came from its alternative sense in Latin, “portcullis”, through French through the notion of “obstruction”, in this case, of vision.[2]
