釘橜（上丁定反考聲以丁釘木也下其月反韻略云杙也爾雅云在地者謂之臬郭璞注云即門橜也或作橛字）。

釘橜 (the first character is d[īng] + d[ìng] fanqie; the Kaosheng says: "To nail wood with nails." The second character is q[í] + yu[è] fanqie; the Yunlüe says: "A stake." The Erya states: "That which is in the ground is called a niè." Guo Pu's commentary notes: "Namely a door stake; sometimes written with the character 橛").
