High-ranking ecclesiastic not yet dead? (7)
I believe the answer is:
prelate
'high-ranking ecclesiastic' is the definition.
(I've seen this in another clue)
'not yet dead?' is the wordplay.
'not yet' becomes 'pre' (I've seen this in other clues).
'dead?' becomes 'late' (similar in meaning).
'pre'+'late'='PRELATE'
(Other definitions for prelate that I've seen before include "Senior member of the clergy" , "Cleric" , "Bishop or other ecclesiastical dignitary" , "e.g. Bishop" , "Church high-ranker" .)
