猜疑（上采灾反杜注左傳云猜疑也方言猜恨也說文猜恨賊也從犬青聲也下魚期反考聲止也貳也未定也古作𠤗亦作𰅢今從吳音疎[上/矢]聲也）。

猜疑 [Suspicion and doubt] (The first character is cai + zai fan. Du's commentary on the Zuo zhuan says: '猜 means to suspect.' The Fangyan says: '猜 means resentment.' The Shuowen says: '猜 means resentful injury.' It is from 犬 [dog] with 青 as phonetic. The second character is yu + qi fan. The Kaosheng says: 'To stop; to be double-minded; undetermined.' In ancient script it was written as 𠤗, also as 𰅢. Today it follows the Wu pronunciation, with shu and [上/矢] as phonetic).
