See man on board, one entering church (9)
I believe the answer is:
bishopric
'see' is the definition.
(thesaurus)
'man on board one entering church' is the wordplay.
'man on board' becomes 'bishop' (chess).
'one' becomes 'i' (Roman numeral).
'entering' indicates putting letters inside.
'church' becomes 'rc' (abbreviation for Roman Catholic).
'i' put inside 'rc' is 'ric'.
'bishop'+'ric'='BISHOPRIC'
(Other definitions for bishopric that I've seen before include "See - diocese" , "Phobic sir (anag)" , "position of a minister" , "Episcopate" , "Church office" .)
