Fake priest will ignore article (4)
I believe the answer is:
sham
'fake' is the definition.
('sham' can be a synonym of 'fake')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sham that I've seen before include "Pretence; bogus, false" , "Phoney sort of hams" , "Counterfeit, fake" , "Mash, being counterfeit" , "charade" .)
