稽顙（溪禮反借用字也孔注尚書云稽首首至地也鄭注周禮云稽首頭至地拜也說文從首𣅀聲古文正體[((巨-匚)/日)*(首-目+日)]首字也經作稽本音雞相傳借用久矣下桑朗反方言顙額也何休注公羊傳云稽顙若今之叩頭於地）。

稽顙 (fanqie: 溪 + 禮; a borrowed character. Kong's commentary on the Shangshu says: "稽首 means the head touching the ground." Zheng's commentary on the Zhouli says: "稽首 is a bow with the head reaching the ground." The Shuowen says: "It is classified under head (首) and takes 𣅀 as phonetic." The orthodox ancient form is [((巨-匚)/日)*(首-目+日)], which is the character for head. The sūtra writes it as 稽, whose original pronunciation is jī; it has long been borrowed by tradition. The second character has the fanqie: 桑 + 朗; the Fangyan says: "顙 means forehead." He Xiu's commentary on the Gongyang zhuan says: "稽顙 is like the present-day knocking of the head upon the ground.")
