Clergyman's extract from sermon's ignored (9)
I believe the answer is:
monsignor
'clergyman's' is the definition.
(Monsignor is an example)
'extract from sermon's ignored' is the wordplay.
'extract from' indicates a hidden word (I've seen this in other clues).
'MONSIGNOR' can be found hidden inside 'sermons ignored'.
(Other definitions for monsignor that I've seen before include "RC dignitary" , "High-ranking RC priest" , "Title of certain Catholic priests and officials" , "Religious title" , "What one may call priest" .)
