Wrong since exposed by cycling clergyman (9)
I believe the answer is:
incorrect
'wrong' is the definition.
(synonyms)
'since exposed by cycling clergyman' is the wordplay.
'since' becomes 'seeingas' (I've seen this in another clue).
'exposed' says to take the centre (the inside of the word is exposed).
'by cycling clergyman' becomes 'correct' (I can't explain this - if you can you should believe this answer much more).
The central letters of 'seeingas' are 'in'.
'in'+'correct'='INCORRECT'
Can you help me to learn more?
(Other definitions for incorrect that I've seen before include "Erroneous" , "False, wrong" , "Place of refuge" , "Not accurate" .)
