灘渚（上他單反玉篇云河灘也爾雅曰太歲在申曰涒灘下章與反爾雅云水中可居者曰洲小洲日渚小渚曰沚又作陼音同上沚音止）。

灘渚 (The first character has the fanqie ta + dan. The Yupian says: 'A river rapid.' The Erya says: 'When the Year Star is in Shen, it is called Tuntan.' The second character has the fanqie zhang + yu. The Erya says: 'Land in water where one can dwell is called an islet (zhou); a small islet is called a zhu; a very small islet is called a zhi.' It is also written as 陼, with the same pronunciation as above. 沚 has the sound zhi).
