[羍*(看-目)*(乳-孚)]珽（上正執字也下汀井反鄭注禮記云珽亦笏也言挺然無所屈也說文云珽大圭也長三尺古用八寸尺即今二尺四寸也從玉廷聲也）。

執珽 (The first is the standard character 執. The second is pronounced with the fanqie 汀 + 井. Zheng's commentary to the Liji states: "The ting is also an official tablet [笏]; it expresses standing upright without yielding." The Shuowen states: "Ting is a large jade tablet, three feet long; in antiquity an eight-inch foot was used, which corresponds to two feet four inches today; it is formed from 'jade' [玉] with 'court' [廷] as phonetic").
