擾動（而沼反擾亂也從手夒聲也夒音奴刀反夒者獸名立字形之本意也篆書取勢分頁下兩點兩邊垂下左右從止已下從夂作夒遂與憂字上下相似後因草書務從省略寡聞之士不曉本字便相效從憂故有斯謬此失之由其來遠矣哀哉實難改正也頁音頡夂音雖也）。

擾動 (Disturb and agitate: with the fanqie 而 + 沼 [rǎo]. Rǎo means confusion and disorder. Composed of 手 with 夒 phonetic. 夒 has the fanqie 奴 + 刀 [náo]. 夒 is the name of a beast, the original idea in constructing the character form. The seal script created the form by dividing the two dots below 頁, letting them hang down on both sides, with 止 on the left and right, and 夂 below, making 夒. Consequently, its upper and lower parts resembled the character 憂 (yōu). Later, because cursive script strove for abbreviation, men of scant learning did not understand the original character and imitated each other by writing it with 憂; hence this error arose. The origin of this mistake goes back far! Alas, it is truly difficult to correct. 頁 has the fanqie 頡 [xié]; 夂 has the fanqie 雖 [suī]).
