Disciple, adherent (8)
I believe the answer is:
follower
I believe this is a double definition.
'disciple' is the first definition.
(I've seen this before)
'adherent' is the second definition.
(I've seen this before)
(Other definitions for follower that I've seen before include "Disciple" , "A loyal adherent - or a pursuer" , "Person who succeeds" , "One accepts the leadership of another" , "Attendant" .)
