羽檄（上王句反說文云鳥羽也下胡狄反爾雅云無枝為檄也說文云符檄三尺書也從木激省聲或從手非）。

Feathered dispatch (羽檄: the first character is [pronounced with the fanqie] wang + ju; the Shuowen says it means bird feathers; the second character is [pronounced with the fanqie] hu + di; the Erya says: "A branchless [wooden tablet] is a xi"; the Shuowen says: "A military dispatch is a three-foot wooden tablet"; it is formed from wood [木] with the abbreviated form of ji [激] as phonetic; some write it with hand [手], which is incorrect).
