Coming from abroad, her enthusiastic follower (8)
I believe the answer is:
adherent
'follower' is the definition.
(I know that adherent is a type of follower)
'coming from abroad her enthusiastic' is the wordplay.
'coming from' indicates the answer is hidden within the clue.
'ADHERENT' is hidden within 'abroad her enthusiastic'.
(Other definitions for adherent that I've seen before include "Loyal follower, one who sticks" , "Disciple, follower" , "Supporter, fan" , "lover" , "Devotee" .)
