茵蓐（上於真反下如欲反毛詩傳曰茵虎皮也玉篇云以虎皮為蓐曰茵又作鞇郭注尒雅曰蓐席也聲類曰蓐薦也又作褥字同案茵蓐二字若以皮為即從艸作若以革為即從革作鞇也）。

茵蓐 (The first character is pronounced with the fanqie *y-*, [yin], from 於 and 真. The second character is pronounced with the fanqie *r-*, [ru], from 如 and 欲. The commentary to the *Mao Shi* states: '茵 means tiger skin.' The *Yupian* states: 'Using tiger skin as a mat is called 茵.' It is also written as 鞇. Guo's commentary on the *Erya* states: '蓐 means a mat.' The *Shenglei* states: '蓐 means bedding.' It is also written as 褥, which is the same character. Note: for the two characters 茵 and 蓐, if made of skin, they are written with 艸 [grass]; if made of leather, they are written with 革 as 鞇.)
