Like pale dam on Nile (5)
I believe the answer is:
aswan
'dam on nile' is the definition.
'aswan' can be an answer for 'dam' (I've seen this before). I am unsure of the 'on nile' bit.
'like pale' is the wordplay.
'like' becomes 'as'.
'pale' becomes 'wan' (wan can mean pale or grey).
'as'+'wan'='ASWAN'
Can you help me to learn more?
(Other definitions for aswan that I've seen before include "Egyptian city and dam" , "Large dam in Egypt" , "Site of dam in Egypt" , "Egyptian town and dam" , "Nile High Dam" .)
