Don't let out about, to the newspapermen (7)
I believe the answer is:
repress
'don't let' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Maybe you can see a link between them that I can't see?
'about to the newspapermen' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'to the newspapermen' becomes 'press' (I can't explain this - if you can you should give a lot more credence to this answer).
're'+'press'='REPRESS'
'out' is the link.
Can you help me to learn more?
(Other definitions for repress that I've seen before include "Restrict freedom of" , "bottle up" , "Put in irons, maybe" , "Check" , "Silence" .)
