Accepted award (briefly revealing behind) (5)
I believe the answer is:
abaft
'behind' is the definition.
(I've seen this before)
'accepted award briefly' is the wordplay.
'accepted' becomes 'a' (financial abbreviation).
'award' becomes 'bafta' (British Academy of Film and Television Arts award).
'briefly' means to remove the last letter.
'bafta' with its final letter taken away is 'baft'.
'a'+'baft'='ABAFT'
'revealing' acts as a link.
(Other definitions for abaft that I've seen before include "nearer the stern" , "To the rear" , "near end of Titanic?" , "Towards the stern of a boat" , "Astern, at sea" .)
