U+668D "暍" CJK Unified Ideograph-# Unicode Character
U+668D "暍" CJK Unified Ideograph-# is a rare and archaic Chinese character that primarily means "sunstroke" or "heatstroke" resulting from exposure to intense sunlight, often used in classical texts to describe a person overcome by heat. It comprises the radical 日 (sun) on the left, indicating a connection to sunlight or daytime, and the phonetic component 曷 on the right, which hints at its pronunciation like "he" or "ye" in Middle Chinese. This character appears in historical writings such as the ancient Chinese medical text the Huangdi Neijing, where it refers to a condition of severe overheating. Its usage has largely fallen out of modern everyday language, making it a lexicographical rarity preserved mainly in specialized dictionaries or historical literature.
