U+81DF "臟" CJK Unified Ideograph-# Unicode Character
U+81DF "臟" CJK Unified Ideograph-# is a Chinese character that primarily refers to an internal organ, specifically the viscera or entrails of the body, such as the heart, liver, spleen, lungs, and kidneys, collectively known as the zang organs in traditional Chinese medicine. This character is composed of the radical for meat or flesh (月) on the left, indicating its association with the body, and a phonetic component on the right derived from the character for treasure or storehouse (臧), which hints at its semantic sense of internal storage or concealment. In modern usage, it appears in words like 內臟 (nèizàng) for internal organs and 臟腑 (zàngfǔ) for the organ systems, and it is contrasted with the character 髒 (zāng, meaning dirty) due to similar pronunciation in Mandarin, though they are distinct in writing and meaning.
