浮囊（附無反。玉篇音扶尤反陸法言音薄謀反下二皆吳楚之音也。今並不取。廣雅浮漂也。鄭注禮記在上曰浮。賈逵浮輕也。說文浮泛也。從水孚聲也。下乃郎反。集訓云有底曰囊。無底曰橐。皆盛物器也。字書云大曰囊小曰橐。此說非也。小篆囊字從㯻省從𱔞從衣[咒-几+(卄/井)]亦聲也。今經言浮囊者氣囊也。欲渡大水假此氣囊輕浮之力。故說為喻也。橐音託。㯻音混。[咒-几+(卄/井)]音女耕反）。

Float bladder (浮囊): Fú has the fanqie fu + wu (fú). The Yupian gives the pronunciation fu + you (fóu), and Lu Fayan gives the pronunciation bo + mou (póu); the latter two are regional dialects of Wu and Chu, which are not adopted here. The Guangya says: ‘Fú means drifting.’ Zheng's commentary on the Liji says: ‘Being on top is called fú.’ Jia Kui says: ‘Fú means buoyant and light.’ The Shuowen says: ‘Fú means floating; it takes “water” (水) with fú (孚) as phonetic.’ The lower character has the fanqie nai + lang (náng). The Jixun says: ‘Having a bottom is called náng (bag); having no bottom is called tuó (sack); both are receptacles for holding things.’ The Zishu says: ‘A large one is called náng, a small one is called tuó,’ but this explanation is incorrect. The small seal form of the character náng takes an abbreviated gǔn (㯻), 𱔞, and yī (衣), with [咒-几+(卄/井)] also as phonetic. What the sūtras currently call a “floating sack” is an air bladder. One wishing to cross a great water relies on the buoyant lightness of this air bladder, hence it is used as a metaphor. Tuó (橐) is pronounced tuo (tuō); 㯻 is pronounced hun (hùn); [咒-几+(卄/井)] has the fanqie nü + geng (nǐng).
