zhàng cataract in the eye

Etymology

About

is a phono-semantic compound used exclusively in medical vocabulary. It combines the semantic radical (mù, 'eye'), situating it in the realm of vision, with the phonetic component (zhāng), which provides its pronunciation. The character refers to an eye disease, specifically a cataract or visual obstruction. This precise term appears in traditional medical encyclopedias, diagnostic manuals, and records of visual impairment, without ever entering colloquial speech.
