Generous gift (8)
I believe the answer is:
largesse
'generous gift' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for largesse that I've seen before include "Liberal gift" , "Generous disposal of gifts" , "Generosity in bestowing gifts" , "Bounty, gift" , "Generosity in gift-giving" .)
