Dog made a meal of the cleric! (6)
I believe the answer is:
curate
'the cleric' is the definition.
(I've seen this before)
'dog made a meal of' is the wordplay.
'dog' becomes 'cur' (both can mean a despicable person).
'made a meal of' becomes 'ate' (I've seen this in another clue).
'cur'+'ate'='CURATE'
(Other definitions for curate that I've seen before include "assistant rector" , "Priest, a vicar's assistant" , "Organize a museum or exhibition" , "Assistant to a parish priest" , "Parish priest's assistant" .)
