* 《一切经音义》: 也説文～蛘也从虫羊声经文从疒作痒是病也非经意

(translated) According to *Yiqiejing Yinyi* and *Shuowen*, it means 蛘 (yáng), which is a type of insect; It is a phono-semantic character, formed from the radical "虫" (insect) and the phonetic component "羊" (yáng); In sutra texts, it is mistakenly written with the sickness radical "疒" as 痒 (yǎng), which means sickness and is not the intended meaning in the sutras
