7.87

𤸃極（色甃反爾雅瘦瘠也音藉文字集略云肌肉減耗也說文瘦臞也正體作𤸃今通作瘦俗字也爾雅臞瘠也說文云瘠少肉也從疒叜聲也）。

Extremely emaciated (𤸃極; se + zhou fanqie. The Erya says: "Shou (瘦) means emaciated (ji, pronounced ji)." The Wenzi jilüe says: "Depletion of muscle and flesh." The Shuowen says: "Shou means gaunt (qu)." The standard form is written 𤸃; nowadays it is commonly written 瘦, which is a vulgar character. The Erya says: "Qu means emaciated." The Shuowen says: "Ji means little flesh." It takes the sickness radical (疒) with sou (叜) phonetic.).
