魚鼈（上語居反說文水蟲也尒雅云魚尾謂之丙郭注云似篆書丙字俗作魚字下鞭滅反說文云水介蟲也從黽敝聲也經文從魚作鱉俗字也黽音猛）。

Fish and softshell turtle (魚鼈: the upper character has the fanqie 語居. The Shuowen says: "An aquatic creature." The Erya says: "The tail of a fish is called bǐng." Guo [Pu]'s commentary says: "It resembles the seal-script character bǐng (丙); colloquially written as the character yú (魚)." The lower character has the fanqie 鞭滅. The Shuowen says: "A shelled aquatic creature. Formed with [the semantic element] mǐn (黽) and [the phonetic element] bì (敝)." In the sūtra text it is written with 'fish' (魚) as 鱉, which is a vulgar character. Mǐn is pronounced měng).
