With money we brought back nut (6)
I believe the answer is:
cashew
'nut' is the definition.
(I know that cashew is a type of edible nut)
'with money we brought back' is the wordplay.
'with' is a charade indicator (letters next to each other).
'money' becomes 'cash' (cash is a type of money).
'brought back' shows that the letters should be reversed in order.
'we' reversed gives 'ew'.
'cash' next to 'ew' is 'CASHEW'.
(Other definitions for cashew that I've seen before include "Kind of nut" , "snack perhaps" , "Kidney-shaped nut of tropical tree" , "Edible nut" , "nut-tree" .)
