Censure part of speech splitting Parisian from church (8)
I believe the answer is:
denounce
'censure' is the definition.
(I've seen this in another clue)
'part of speech splitting parisian from church' is the wordplay.
'part of speech' becomes 'noun' (noun is a kind of part of speech).
'splitting' is an insertion indicator.
'parisian from' becomes 'de' ('from' in French).
'church' becomes 'CE' (abbreviation for Church of England).
'de'+'ce'='dece'
'noun' going into 'dece' is 'DENOUNCE'.
(Other definitions for denounce that I've seen before include "Accuse publicly" , "Speak publicly against, expose" , "Criticise or condemn" , "Openly deplore" , "Speak violently against" .)
