Somehow enrol hermit (5)
I believe the answer is:
loner
'hermit' is the definition.
(I've seen this in other clues)
'somehow enrol' is the wordplay.
'somehow' is an anagram indicator.
'enrol' with letters rearranged gives 'LONER'.
(Other definitions for loner that I've seen before include "Antisocial person" , "Recluse" , "One lacking friends" , "Unaccompanied chap" , "Unsociable person" .)
