38.7

[企-止+皂]㳄者（中羨延反說文云㳄口液也從水欠聲或作𰜂古字也經作涎變古字易左為右也）。

Salivating (𰞥㳄者: the middle character has the fanqie [s- + -ian] 羨延. The Shuowen says: ‘㳄 means saliva from the mouth; it takes “water” as its radical and 欠 as its phonetic component.’ It is also written 𰜂, which is an archaic form. The sūtra writes it 涎, modifying the archaic character by swapping the left and right components.)
