15.109

[跳-兆+專]腸（上常兖反說文足腓腸也從足專聲又說文專字從叀寸或作腨俗也下膓音長從肉從易省聲）。

Calves (𧿲腸: the first character has the fanqie 常兖. The Shuowen says: "The fleshy belly of the leg [calf]." It takes 足 as radical with 專 for phonetic value. The Shuowen also notes that the character 專 is composed of 叀 and 寸; it is also written 腨, which is vulgar. The second character 膓 is pronounced 長, composed of 肉 with 易 abbreviated for phonetic value).
