Awards no marks (6)
I believe the answer is:
oscars
'awards' is the definition.
(the Oscars are the Academy Awards)
'no marks' is the wordplay.
'no' becomes 'o' (resembles 0 - 'no' can mean 'zero').
'marks' becomes 'scars' ('scar' can be a synonym of 'mark').
'o'+'scars'='OSCARS'
(Other definitions for oscars that I've seen before include "American Academy Awards" , "Hollywood Academy Awards" , "Cinema's Academy Awards" , "Trophies" , "annual handouts" .)
