Cataract
noun /ˈkætərækt/ — A large, powerful waterfall — or the clouding of vision that mimics its roar.
Definition
A large waterfall; a sudden rush of water in a waterfall formation; also, a medical condition in which the lens of the eye becomes progressively opaque, impairing vision.
Beyond the definition
The two meanings of cataract are connected by an ancient image — the water pouring over the eye, the clouding that arrives like water obscuring what was clear. Both meanings involve something being overwhelmed by force.
Origin & history
From Greek katarrakt s — down-rushing (from kata: down + arassein: to dash). What rushes down — the falling water, and by medical extension, the clouding that obscures vision like a veil of water.
