Product of a fruitful harem? (7)
I believe the answer is:
sultana
'fruitful harem?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'product of a' is the wordplay.
'product of' becomes 'sultan' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sultan'+'a'='SULTANA'
Can you help me to learn more?
(Other definitions for sultana that I've seen before include "sovereign's woman" , "Sovereign's mother perhaps" , "Dry seedless grape" , "concubine?" , "Dried white grape" .)
