[刀/肉/火]鼈（上正體魚字也說文從刀象形火魚尾魚尾與鷰尾相似偶然如火字非從火字也下鞭滅反考聲云水蟲也說文水介蟲也從黽音猛敝聲也經中從魚作鱉俗字非也敝音與上同也）。

[刀/肉/火]鼈 (The upper character is the standard form of the character 魚 ('fish'). The Shuowen jiezi says it is formed from 刀 as a pictograph; 火 represents the fish's tail. The fish's tail resembles a swallow's tail and accidentally looks like the character 火, but it is not formed from the character 火 ('fire'). The lower character is pronounced bie1 [bian-mie fan]. The Kaosheng says: 'An aquatic creature.' The Shuowen jiezi says: 'An aquatic shelled creature; formed from 黽 (pronounced meng3) with 敝 as phonetic.' In the sūtra it is written as 鱉 with 'fish' (魚), which is an incorrect vulgar character. The sound of 敝 is the same as the above).
