捶楚（上佳蘂反國語曰鞭捶使之是也說文捶以杖擊也從手垂聲或從木亦通或曰摘也下初所反毛詩傳楚木名也鄭注禮記云楚荊也說文叢木也從林疋聲疋音疎又音所）。

Beating and caning (捶楚: the first character has the fanqie ji[ā] + [ru]ǐ; the Guoyu says: "Whipping and caning them into service"; this is it. The Shuowen says: "Chui (捶) means to strike with a staff"; it has the hand radical and the phonetic chui (垂); or with the tree radical, which is also acceptable; others say it means to pluck. The second character has the fanqie ch[ū] + [su]ǒ; the Mao commentary on the Shijing says: "Chu (楚) is the name of a wood." Zheng's commentary on the Liji says: "Chu is the chaste tree (vitex)." The Shuowen says: "Thicket"; it has the grove radical and the phonetic shu/suo (疋); 疋 has the sound shu, and also the sound suo).
