Facing defrocked reverend running amok (6)
I believe the answer is:
veneer
'facing' is the definition.
(synonyms)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for veneer that I've seen before include "Superficial veneer" , "Evener (anag.)" , "Thin layer of fine wood covering surface of cheaper wood" , "Superficial polish" , "A thin outer layer" .)
