Private post some read isn't made public (9)
I believe the answer is:
disclosed
'made public' is the definition.
(I've seen this in another clue)
'private post some read isn't' is the wordplay.
I cannot really see how this works, but
'private' could be 'close' (close can mean private or intimate) and 'close' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for disclosed that I've seen before include "Made known" , "Revealed" .)
