拘羑（上音俱考聲拘局也擁也說文執也從手句聲下音酉古獄名也在蕩陰文王所囚之處也說文進善從羊久聲或作羌亦通有作牖非此用也）。

拘羑 (The first character is pronounced jū. The Kaosheng says: "拘 means confined; detained." The Shuowen jiezi says: "To seize. Formed from 手 with 句 phonetic." The second character is pronounced yǒu: an ancient prison name, located in Dangyin, the place where King Wen was imprisoned. The Shuowen jiezi says: "To promote goodness. Formed from 羊 with 久 phonetic." It is also interchangeably written as 羌. Some write 牖, which is not applicable here.)
