Correspond with Grant (6)
I believe the answer is:
accord
I believe this clue is a double definition.
'correspond' is the first definition.
(according is a kind of corresponding)
'grant' is the second definition.
('accord' can be a synonym of 'grant')
'with' acts as a link.
(Other definitions for accord that I've seen before include "Harmony and fellowship" , "Correspond" , "Agree" , "Official treaty" , "Myra -, pianist; Rudolf -, Nazi" .)
