Accept grant (5)
I believe the answer is:
admit
I believe this clue is a double definition.
'accept' is the first definition.
(I know that accept is a more specific form of accept)
'grant' is the second definition.
(grant can mean to agree or admit something)
(Other definitions for admit that I've seen before include "Allow to enter; own up" , "Confess - acknowledge" , "Profess" , "Disclose" , "Provide student with place" .)
