Ruler with a bit of fruit (7)
I believe the answer is:
sultana
'bit of fruit' is the definition.
'sultana' can be an answer for 'fruit' (sultana is a kind of fruit). I'm unsure of the 'bit of' bit.
'ruler with a' is the wordplay.
'ruler' becomes 'sultan' (sultan is a kind of ruler).
'with' is a charade indicator (letters next to each other).
'sultan'+'a'='SULTANA'
Can you help me to learn more?
(Other definitions for sultana that I've seen before include "Pale seedless raisin" , "Wife of an Eastern potentate" , "pudding ingredient" , "Aunt Sal (anag)" , "mistress abroad" .)
