循機（隨遵反爾雅循自也郭璞云自猶從也考聲云循順也說文循行也從彳丑亦反盾聲音脣淮反象形下幾希反孔注尚書云弩牙也制動也說文主發謂之機）。

循機 (s-[ui]-z-[un] fan. The Erya says: '循 means from.' Guo Pu says: 'From is akin to following.' The Kaosheng says: '循 means to comply.' The Shuowen jiezi says: '循 means to patrol; it derives from 彳, ch-[ou]-y-[i] fan, and the sound of 盾, ch-[un]-h-[uai] fan, a pictograph.' The lower character is j-[i]-x-[i] fan. Kong's commentary on the Book of Documents says: 'The trigger-tooth of a crossbow, controlling release.' The Shuowen jiezi says: 'That which directs release is called the trigger (機)').
