Fruit old queen put in stirred neat gin (9)
I believe the answer is:
tangerine
'fruit' is the definition.
(tangerine is a kind of fruit)
'old queen put in stirred neat gin' is the wordplay.
'old queen' becomes 'ER' (Elizabeth Regina, ie Queen Elizabeth).
'put in' is an insertion indicator.
'stirred' indicates anagramming the letters.
'neat'+'gin'='neatgin'
'neatgin' anagrammed gives 'tangine'.
'er' inserted within 'tangine' is 'TANGERINE'.
(Other definitions for tangerine that I've seen before include "shade" , "Green tan I change into orange" , "Small orange" , "something juicy being given to press" , "Orange-type fruit" .)
