Publish topless paper (5)
I believe the answer is:
issue
'publish' is the definition.
('issue' can be a synonym of 'publish')
'topless paper' is the wordplay.
'topless' means to remove the first letter.
'paper' becomes 'tissue' (tissue is a kind of paper).
'tissue' with its initial letter taken away is 'ISSUE'.
(Other definitions for issue that I've seen before include "Problem or concern" , "Emanate" , "Topic; send out" , "Important topic for debate" , "Kids" .)
