Previous head of a religious community (5)
I believe the answer is:
prior
I believe this is a double definition.
'previous' is the first definition.
(prior means previous or earlier)
'head of a religious community' is the second definition.
(head of a priory)
(Other definitions for prior that I've seen before include "boss of Monk?" , "Clergyman - earlier" , "head of a religious community" , "Former - holy man" , "head of a house of friars" .)
