Resident entertaining a bishop's relation (9)
I believe the answer is:
narrative
'relation' is the definition.
(I've seen this before)
'resident entertaining a bishop's' is the wordplay.
'resident' becomes 'native' (I've seen this before).
'entertaining' means one lot of letters goes inside another.
'bishop' becomes 'rr' (abbreviation for Right Reverend).
'a'+'rr'='arr'
'native' placed around 'arr' is 'NARRATIVE'.
(Other definitions for narrative that I've seen before include "Tale" , "Verbal account" , "Account describing events" , "Story line" , "Report" .)
