Vouchsafes; concedes (6)
I believe the answer is:
grants
I believe this clue is a double definition.
'vouchsafes' is the first definition.
(I've seen this before)
'concedes' is the second definition.
('grant' can be a synonym of 'concede')
(Other definitions for grants that I've seen before include "Gives formally or allows as privilege" , "Bestows or concedes" , "Donations or subsidies" , "'Subsidies, monetary aid (6)'" , "Awards or bestows" .)
