Awards without marks (6)
I believe the answer is:
oscars
'awards' is the definition.
(the Oscars are the Academy Awards)
'without marks' is the wordplay.
'without' becomes 'o' (I am not sure about this - if you are sure you should believe this answer much more).
'marks' becomes 'scars' ('scar' can be a synonym of 'mark').
'o'+'scars'='OSCARS'
Can you help me to learn more?
(Other definitions for oscars that I've seen before include "Trophies" , "Hollywood annual film awards" , "annual handouts" , "Cinema's Academy Awards" , "Awards, for dramatic achievements" .)
