5.36

或爴（俱籰反王約反字書云攫搏音博也文字音義云鳥窮則啄獸窮則攫俱籰反爪持曰爴又音居碧反亦通）。

Or seize (或爴): Read with the fanqie 俱 + 籰 or 王 + 約. A character dictionary says: 'It means to seize and strike (搏, pronounced like 博).' The Wenzi yinyi says: 'When birds are in distress, they peck; when beasts are in distress, they seize (俱 + 籰 fanqie); holding with claws is called 爴.' It is also pronounced with the fanqie 居 + 碧, which is also acceptable.
