Awards zero marks (6)
I believe the answer is:
oscars
'awards' is the definition.
(Oscar is an example)
'zero marks?' is the wordplay.
'zero' becomes 'o'.
'marks?' becomes 'scars' ('scar' can be a synonym of 'mark'**).
'o'+'scars'='OSCARS'
(Other definitions for oscars that I've seen before include "Movie awards" , "American Academy Awards" , "annual handouts" , "American film Awards" , "Cinema's Academy Awards" .)
