聳翮（古文竦𢥠慫三形今作聳同先勇反聳謂前上也下胡革反尒雅羽本謂之翮鳥羽根也說文羽莖也）。

聳翮 (The ancient script has the three forms 竦, 𢥠, and 慫; today it is written 聳, all identical, with the fanqie 先勇 [sǒng]. 聳 means to rise forward and upward. The second character has the fanqie 胡革 [hé]. The Erya states: 'The base of a feather is called 翮; it is the quill root of a bird's feather.' The Shuowen jiezi states: 'The quill stem of a feather.')
