To censure or preach perhaps (8)
I believe the answer is:
reproach
'to censure' is the definition.
(I've seen this before)
'or preach perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'or'+'preach'='orpreach'
'orpreach' anagrammed gives 'REPROACH'.
(Other definitions for reproach that I've seen before include "carpet" , "criticise" , "Chide" , "Admonition" , "Upbraid, rebuke" .)
