一切經音義 1.106

1.106

胷臆（上香邕反說文胷膺也案膺即臆也或作匈亦通下應力反說文臆亦胷骨也從肉從億省聲也經從月誤也）。

Xiongyi (chest and breast) (the first character is xiang-yong fan; the Shuowen says: "Xiong means ying [breast]"; examining this, ying is precisely yi; it is also written as 匈; the second character is ying-li fan; the Shuowen says: "Yi is also the chest bone; derived from 肉 with an abbreviated 億 as phonetic"; the scripture writes it with 月, which is erroneous).
