Aswan deteriorates? Here's compensation! (7)
I believe the answer is:
damages
'compensation' is the definition.
(damages is a kind of compensation)
'aswan deteriorates?' is the wordplay.
'aswan' becomes 'dam' (I can't explain this - if you can you should believe this answer much more).
'deteriorates?' becomes 'ages' (ageing is a kind of deteriorating).
'dam'+'ages'='DAMAGES'
'here's' acts as a link.
Can you help me to learn more?
(Other definitions for damages that I've seen before include "Hurts" , "Money awarded as compensation" , "Harms" , "Moneys paid as compensation for an injury" , "weakens" .)
