Papal Order admitted sharing Latin publication (8)
I believe the answer is:
bulletin
'sharing latin publication' is the definition.
'bulletin' can be an answer for 'publication' (thesaurus). I am not sure about the 'sharing latin' bit.
'papal order admitted' is the wordplay.
'papal order' becomes 'bullet' (I can't explain this - if you can you should give a lot more credence to this answer).
'admitted' becomes 'in' (eg someone might be admitted into a group).
'bullet'+'in'='BULLETIN'
Can you help me to learn more?
(Other definitions for bulletin that I've seen before include "Regular newsletter" , "Regular report" , "Short and regular up-date" , "Short statement on the news as it happens" , "Report for publication or broadcast" .)
