35.56

欬遬（上開愛反說文氣逆也從欠亥經文從口作咳音孩小兒笑也非此義也下叟奏反考聲云氣衝喉也經中亦從口作嗽俗用非正體也）。

Coughing (The first character is kāi + ài fanqie. The Shuowen says: 'Counter-flow of breath.' It takes 'yawn' and hài. In the sūtra text it is written with 'mouth' as 咳, pronounced hái, meaning a child's laugh, which is not this meaning. The second character is sǒu + zòu fanqie. The Kaosheng says: 'Breath rushing against the throat.' In the sūtra it is also written with 'mouth' as 嗽, which is a vulgar usage and not the orthodox form).
