About
The character "翳" is structured with "羽" meaning feathers at its base and "殹" above, which itself combines "医" suggesting concealment and "殳" representing a tool, together implying an act of covering or obscuring. Etymologically, it initially referred to a feathered canopy or screen used for shading. Over time, its meaning broadened from physical covering to general obscuration, and later specialized in medical contexts to denote a cataract, an ocular opacity that impedes vision.
