嘯和（上蘇弔反說文云呼吟也謂聚辱出聲也亦作歗下胡臥反尒雅曰徒吹謂之和即應和也）。

嘯和 (The first character is pronounced with the fanqie *x-*, [xiao], from 蘇 and 弔. The *Shuowen* states: 'It means to whistle or hum; that is, to gather the lips and produce a sound.' It is also written as 歗. The second character is pronounced with the fanqie *h-*, [he], from 胡 and 臥. The *Erya* states: 'Blowing solely with the mouth is called 和; that is, responding in harmony.')
