胞胎（上已交反古文本作包象形字也石經作胞相傳音為普包反非也說文云婦人懷姙而甚反兒生衣也從勹音包從已音似在勹中象子未成形字也孔注尚書云包裹也下他來反說文云女人懷姙未生也從肉台聲也）。

Embryo and womb (胞胎: for the first character, the fanqie is 已交 [bāo/qiāo]. Ancient texts originally wrote 包, a pictographic character. The Stone Classics write it 胞, traditionally pronounced 普包 [pāo], which is incorrect. The Shuowen says: 'It refers to a woman conceiving a pregnancy, and the afterbirth (兒生衣) when a child is born. It takes radical 勹 [bāo] and radical 巳 [sì] inside 勹, depicting the child not yet fully formed into a character.' Kong [Anguo]'s commentary on the Shangshu says: 'It means to wrap around.' For the second character, the fanqie is 他來 [tāi]. The Shuowen says: 'A woman's pregnancy before giving birth. It takes radical 肉 [flesh] with 台 as phonetic').
