囹圄（上歷丁反下魚舉反獄名周禮三王始有獄釋名云囹領也圄禦也謂領錄囚徒御禁之說文云囹獄也圄守也外形內聲字）。

Prison (囹圄: the first character has the fanqie 歷丁 [li + ding / líng]; the second character has the fanqie 魚舉 [yu + ju / yǔ]. Names for a prison. In the Zhouli, prisons first appeared under the Three Kings. The Shiming says: "'囹' means to receive and record; '圄' means to ward off; that is, to register prisoners and hold them in custody." The Shuowen says: "'囹' means prison; '圄' means to guard." These are characters with the form on the outside and the phonetic component on the inside.)
