6.204

蟠於（上伴僈反廣雅云蟠曲也方言云龍未昇天蟠在穴中謂之蟠龍也說文從虫從番聲番音同上僈音母官反）。

蟠於 (The first character has the fanqie ban + man; the Guangya says: “Pan means coiled.” The Fangyan says: “When a dragon has not yet ascended to heaven, it coils in a cave; it is called a coiled dragon (panlong).” The Shuowen says: “Composed of the insect radical (虫) with fan as phonetic.” Fan has the same sound as above; man has the fanqie mu + guan.)
