Some academic once denied a grant (7)
I believe the answer is:
'a grant' is the definition.
(I've seen this before)
'some academic once denied' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'CONCEDE' is hidden in the letters of 'academic once denied'.
(Other definitions for concede that I've seen before include "Admit; yield" , "Surrender, yield" , "Make concession" , "Yield; grant" , "Acknowledge - abandon" .)
