䶤

It names the sound of gnawing bone.

The early Chinese dictionary Shuowen Jiezi lists 䶤 as a headword; the work was compiled in the Eastern Han, around 100–121. The form combines 齒, “teeth,” and 骨, “bone”; 骨 serves as its sound component.

Quli, a chapter of Liji, an old Chinese book of rites, discourages gnawing bones at the table because the noise was disrespectful. 䶤 names that particular sound, not eating in general. Later reference works—the Kangxi Dictionary and the rhyme dictionary Guangyun—preserve the narrow sense and connect 𩪲 as a written variant.
