門閫（下苦本反切韻云閫門限也案爾雅云橛謂之𨵚郭璞注即門閫也今案則門中心礙門木）。

門閫 (The second character is pronounced 苦 + 本 fanqie. The Qieyun says: 'Kun means a door threshold.' Examining the Erya: 'A door-stop is called a jue [𨵚].' Guo Pu's commentary says: 'That is the door threshold.' Examining it now, it is the wood in the center of the doorway that blocks the doors).
