Art of journalists suppressing noise of pain (7)
I believe the answer is:
prowess
'art' is the definition.
(I know that art can be written as prowess)
'journalists suppressing noise of pain' is the wordplay.
'journalists' becomes 'press' (the press can mean the newspaper industry).
'suppressing' means one lot of letters goes inside another.
'noise of pain' becomes 'ow' (I can't explain this - if you can you should believe this answer much more).
'press' enclosing 'ow' is 'PROWESS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for prowess that I've seen before include "Skill in a particular field" , "Accomplishment" , "courage" , "Skill, expertise; bravery" , "'Skill, expertise (7)'" .)
