胞胎（上補交反古文作包象形字也為是胎衣蔡邕石經加肉作胞說文云兒生衣也孔注尚書云裹也莊子云胞者腹肉衣也俗音普包反非也下他來反廣雅婦人孕二月為胎說文云婦孕二月也蒼頡篇云女人懷妊未生曰胎從肉台聲也裹音果）。

胞胎 (The upper character is pronounced 補 + 交 fanqie. The ancient form is written as 包, which is a pictograph; because it is the afterbirth, Cai Yong's Stone Classics added 肉 to write it as 胞. The Shuowen says: 'The garment in which a child is born.' Kong's commentary on the Shangshu says: 'To wrap.' Zhuangzi says: 'The 胞 is the garment of abdominal flesh.' The popular pronunciation 普 + 包 fanqie is incorrect. The lower character is pronounced 他 + 來 fanqie. The Guangya says: 'When a woman is pregnant for two months, it is 胎.' The Shuowen says: 'A woman's pregnancy of two months.' The Cangjie pian says: 'A woman's conceiving without having yet given birth is called 胎; it derives from 肉 with 台 as phonetic.' 裹 is pronounced 果).
