潬潭（上歎難反尒疋沙水出曰潬形聲字也下音談王逸注楚辭云潭閑也南楚之人謂深水曰潭潭閑也深也亦形聲之字也作灘者非古文之字也）。

潬潭: The first character has the fanqie tan + nan (shàn). The *Erya* says: 'A sandbank emerging from the water is called a shan; a phono-semantic compound character.' The second character is pronounced tan (tán). Wang Yi's commentary to the *Chuci* says: 'Tan means calm and deep.' The people of southern Chu call deep water tan; tan means tranquil and deep; it is also a phono-semantic compound character. Writing it as 灘 is not the ancient character.
