Archdeacon meets gangster open to corruption (5)
I believe the answer is:
venal
'open to corruption' is the definition.
(I've seen this in another clue)
'archdeacon meets gangster' is the wordplay.
'archdeacon' becomes 'ven' (abbreviation for The Venerable).
'meets' says to put letters next to each other.
'gangster' becomes 'al' (Al Capone).
'ven'+'al'='VENAL'
(Other definitions for venal that I've seen before include "motivated by corruption" , "easily bribed" , "Susceptible to bribery" , "Easily corrupted" , "Open to bribes" .)
