Member of abbey busybody reported (5)
I believe the answer is:
prior
'member of abbey' is the definition.
(member of a priory)
'busybody reported' is the wordplay.
'busybody' becomes 'prier' (I've seen this in another clue).
'reported' indicates a 'sounds like' (homophone) clue.
'prier' sounds like 'PRIOR'.
(Other definitions for prior that I've seen before include "Preceding" , "Former - churchman" , "Clergyman - earlier" , "Previous; deputy abbot" , "head of a house of friars" .)
