Try a paper (5)
I believe the answer is:
essay
I believe this is a double definition.
'try' is the first definition.
(essay can mean to try or attempt something)
'a paper' is the second definition.
(I've seen this in another clue)
(Other definitions for essay that I've seen before include "Endeavour" , "Try - composition" , "Written composition" , "Short literary piece: attempt" , "Have a shot at a written piece" .)
