吟嘯（下消弔反字書正從欠作歗云歌也蹙口卷舌出聲也故詩云其歗歌也說文云吟也從欠肅聲傳文作嘯俗字也）。

Chanting and whistling (吟嘯) (the second character is pronounced with the fanqie 消弔 [xiāo + diào -> xiào]; dictionaries properly write it with the lack radical (欠) as 歗, stating that it means singing, or producing sound by puckering the mouth and curling the tongue; thus the Shijing says: 'She whistles and sings'; the Shuowen says: 'It means to chant; it is composed of the lack radical (欠) with 肅 phonetic'; the transmission text writes 嘯, which is a vulgar character).
