Devotee, female, with nothing left, not as tall (8)
I believe the answer is:
follower
'devotee' is the definition.
(I've seen this before)
'female with nothing left not as tall' is the wordplay.
'female' becomes 'f' (common abbreviation).
'with' is a charade indicator (letters next to each other).
'nothing' becomes 'O' (O resembles 0).
'left' becomes 'l' (common abbreviation).
'not as tall' becomes 'lower' (I am not sure about this - if you are sure you should believe this answer much more).
'f'+'o'+'l'+'lower'='FOLLOWER'
Can you help me to learn more?
(Other definitions for follower that I've seen before include "Supporter" , "Person who succeeds" , "A loyal adherent - or a pursuer" , "Disciple" , "Attendant" .)
