U+81AF "膯" CJK Unified Ideograph-# Unicode Character

U+81AF "膯" CJK Unified Ideograph-# is a rare Chinese character that primarily refers to a type of fat or grease, specifically the fat located around the internal organs, such as the kidneys or intestines, and historically appears in classical texts like the Erya dictionary from the Han dynasty. This character combines the semantic radical for meat or flesh, 月, with a phonetic component, 登, to suggest both its biological meaning and its pronunciation, which in modern Mandarin is read as tēng. Although not commonly used in everyday writing today, 膯 serves as a specialized term in ancient Chinese lexical traditions and contributes to the broader system of over 90,000 recorded Chinese characters preserved in the Unicode standard for global digital use.
