5.245

淤埿（上依倨反韻英濁水中泥也下奴低反說文埿塗也從土泥聲經文作泥說文水名也非淤埿也）。

淤埿 (The upper character has the fanqie 依倨 [y- + -(g)wo = yū]; the Yunying says: 'Mud in turbid water.' The lower character has the fanqie 奴低 [n- + -(d)ei = ní]; the Shuowen says: '埿 means mud/mire; it is formed with the classifier 土 [earth] and phonetic 泥.' In the sūtra text it is written as 泥; the Shuowen says this is a name of a river, not mire).
