Concerning a top bishop, parochial epic's sorted out (14)
I believe the answer is:
archiepiscopal
'concerning a' is the definition.
I can't judge whether this definition defines the answer.
'top bishop parochial epic's sorted out' is the wordplay.
'top' means to remove the first letter.
'bishop' becomes 'B' (chess abbreviation).
'sorted out' is an anagram indicator.
'b'+'parochial'+'epics'='bparochialepics'
'bparochialepics' with its initial letter taken away is 'parochialepics'.
'parochialepics' with letters rearranged gives 'ARCHIEPISCOPAL'.
Can you help me to learn more?
(Other definitions for archiepiscopal that I've seen before include "of prelate" , "from York, say" , "from York, perhaps?" .)
