Manage to enrol hermit (5)
I believe the answer is:
loner
'hermit' is the definition.
(I've seen this in another clue)
'manage to enrol' is the wordplay.
'manage' is an anagram indicator (I've seen this in other clues).
'enrol' anagrammed gives 'LONER'.
(Other definitions for loner that I've seen before include "Individualist" , "One preferring own company" , "Isolated individual" , "Antisocial person" , "Person who prefers his own company" .)
