Curmudgeon spotted with daughter out for fruit (4,5)
I believe the answer is:
crab apple
'fruit' is the definition.
(crab apple is a kind of fruit)
'curmudgeon spotted with daughter out' is the wordplay.
I cannot quite understand how this works, but
'curmudgeon' could be 'crab' (I've seen this in another clue) and 'crab' is found in the answer.
The remaining letters 'apple' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
(Other definitions for crab apple that I've seen before include "Small sour version of common orchard fruit" , "Wild fruit used for jam" , "unappetizing fruit" , "Wild fruit for jelly" , "A small sour fruit - will it keep the doctor away?" .)
