Win female author will refuse (8)
I believe the answer is:
landfill
'refuse' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'win female author' is the wordplay.
'win' becomes 'land' (both can mean to secure or obtain).
'female author' becomes 'fill' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'land'+'fill'='LANDFILL'
'will' acts as a link.
Can you help me to learn more?
(Other definitions for landfill that I've seen before include "Rubbish disposal site" , "Method of waste disposal" , "Rubbish buried in site" , "Disposal of waste by burial" , "Buried waste material" .)
