Devotee shaking head over the cost of living somewhere (8)
I believe the answer is:
adherent
'devotee' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for adherent that I've seen before include "Supporter, fan" , "One believes in and helps spread the doctrine of another" , "Person supporting" , "Freak" , "Devotee" .)
