Find fault with herd Preen butchered (9)
I believe the answer is:
reprehend
'find fault with' is the definition.
(I've seen this before)
'herd preen butchered' is the wordplay.
'butchered' is an anagram indicator (I've seen this in other clues).
'herd'+'preen'='herdpreen'
'herdpreen' anagrammed gives 'REPREHEND'.
(Other definitions for reprehend that I've seen before include "Address reprimand to (someone)" , "Rebuke" , "Censure" , "tick off" , "Find fault with" .)
