茵蓐（茵於真反蓐如欲反毛詩傳曰茵虎皮也玉篇曰以虎皮為蓐曰茵字又作鞇郭注爾雅曰蓐席聲類曰蓐薦也案茵蓐二字若以草為之者字即從廾若以皮為之者字即從革其蓐字從衣者葢是通用也）。

Cushions and mats [茵蓐] (yin [茵] is pronounced 於真 [ʔ- + (tɕ)iɪn > yīn]; ru [蓐] is pronounced 如欲 [ɲ- + (j)owk > rù]. The Mao Commentary on the Shijing says: “Yin is tiger skin.” The Yupian says: “Using tiger skin as a mat is called yin; the character is also written 鞇.” Guo's commentary on the Erya says: “Ru is a mat.” The Shenglei says: “Ru is a mattress.” In our text, for the two characters yin and ru, if made of grass they take the grass radical; if made of hide they take the leather radical; that the character ru is written with the clothing radical is because they are interchangeable).
