顛倒（上丁堅反孔注尚書云𠑘覆言反倒也廣雅𠑘倒也馬融注論語僵仆也說文從足作蹎又從走作𧽍或作傎竝通經文通作顛俗用非本字也下當老反考聲倒仆也）。

顛倒 (The upper character is pronounced 丁 + 堅 fanqie. Kong [Anguo]'s commentary on the Shangshu says: '𠑘 means overturned; speaking of being inverted.' The Guangya says: '𠑘 means inverted.' Ma Rong's commentary on the Lunyu says: 'To fall prone.' The Shuowen writes it with 足 as 蹎, and also with 走 as 𧽍, or as 傎; all are interchangeable. In the sūtra text it is generally written as 顛, which is a popular usage and not the original character. The lower character is pronounced 當 + 老 fanqie. The Kaosheng says: '倒 means to collapse').
