崖岸（上五皆反說苑云山邊高險謂之崖說文山高邊也從屵音五割反圭聲也下我幹反崖峻水深曰岸爾雅重崖岸郭注云兩崖累者為岸也）。

Cliffs and riverbanks (the upper character is [pronounced with the fanqie] 五 + 皆. The Shuoyuan says: 'A high, precipitous mountain edge is called an ai (cliff).' The Shuowen says: 'A mountain's high edge; it derives from the cliff radical, pronounced with the fanqie 五 + 割, with gui as phonetic.' The lower character is [pronounced with the fanqie] 我 + 幹. Where cliffs are steep and the water deep, it is called an an (bank). The Erya says: 'Tiered cliffs are an.' Guo's commentary says: 'Two cliffs piled one upon another form an an').
