Fruit and nuts taken back by child (6)
I believe the answer is:
damson
'fruit' is the definition.
(damson is a kind of fruit)
'nuts taken back by child' is the wordplay.
'nuts' becomes 'mad' (informal term).
'taken back' is a reversal indicator.
'by' says to put letters next to each other.
'child' becomes 'son' (male child).
'mad' backwards is 'dam'.
'dam'+'son'='DAMSON'
'and' acts as a link.
(Other definitions for damson that I've seen before include "Small fruit for nomads" , "jam producer" , "sort of fruit" , "Wild plum" , "Sort of plum" .)
