Benefit, asset (4)
I believe the answer is:
boon
I believe this is a double definition.
'benefit' is the first definition.
(a boon is a help or benefit)
'asset' is the second definition.
(I've seen this in another clue)
(Other definitions for boon that I've seen before include "Benefaction" , "Benefit and advantage" , "Godsend" , "Blessing - sort of companion?" , "Blessing, favour" .)
