𧏦動（𨳝尹反考聲云有足曰蟲無足曰𧏦說文小蟲動皃從虫䎡聲經文作𧑮誤也蒼頡篇作[虫*芥]也）。

𧏦動 (ruǎn-dòng; fanqie: [r- + -ǔn] [ruǎn]. The Kaosheng says: 'Those with feet are called 蟲 [insects]; those without feet are called 𧏦 [crawling grubs].' The Shuowen jiezi says: 'The wriggling movement of small insects. It takes 虫 as semantic component and 䎡 as phonetic component.' In the sūtra text it is written as 𧑮, which is erroneous. The Cang Jie pian writes it as [虫*芥].)
