加趺（古遐反尒雅加重也則交坐除災橫經等云結交趺坐是也有趺不知所從俗字也江南謂開膝坐為跘跨坐山東謂之甲趺坐也跘音拔患反跨音口化反）。

Crossed legs [加趺]: ([The fanqie for 加 is] gu + xia. The Erya says: 'jia [加] means doubled' [重]. Thus sitting cross-legged. The Chu zaiheng jing and other sūtras say 'sitting with crossed legs' [結交趺坐]. The character 趺 has an unknown derivation and is a vulgar graph. South of the Yangtze, sitting with knees opened wide is called 'straddle-sitting' [跘跨坐]; east of the mountains it is called 'interlocking-foot sitting' [甲趺坐]. The fanqie for 跘 is ba + huan; the fanqie for 跨 is kou + hua).
