State of fruit ends in great wastage (9)
I believe the answer is:
sultanate
'state' is the definition.
(I know that sultanate is a type of state)
'fruit ends in great wastage' is the wordplay.
'fruit' becomes 'sultana' (sultana is a kind of fruit).
'ends in' says to take the final letters.
The last letters of 'great wastage' are 'te'.
'sultana'+'te'='SULTANATE'
'of' acts as a link.
(Other definitions for sultanate that I've seen before include "Brunei?" , "Country" , "Turkey was" , "Muslim dominion" .)
