Former community superior (5)
I believe the answer is:
prior
I believe this clue is a double definition.
'former' is the first definition.
(both can mean at earlier time)
'community superior' is the second definition.
(head of a religious order)
(Other definitions for prior that I've seen before include "Coming before in time or importance" , "Source of poetry in 17th century" , "Existing earlier" , "head of a house of friars" , "Earlier, coming before another in time" .)
