About

The character for "gums" or "to gnaw" presents a clear example of phonetic and semantic construction in Chinese writing, where its traditional form 齦 is built from the semantic component 齒, meaning "tooth" or "teeth", combined with 艮, which primarily serves as a phonetic indicator suggesting its pronunciation but also carries a connotation of stopping or resistance, possibly alluding to the action of teeth meeting an object. Over time, the core meaning settled on the anatomical "gums", the flesh surrounding the teeth, while the verb sense of "gnawing" became less common in modern usage. In its simplified iteration, 龈, the complex tooth radical 齒 is replaced by the simpler 龰, though the phonetic component 艮 remains, preserving the character's essential linguistic identity while streamlining its form.
