Many an Indian (5)
I believe the answer is:
hindu
'many an indian' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hindu that I've seen before include "Brahma is one of his gods" , "Member of religious group" , "One expecting to be reincarnated" , "Indian religious adherent" , "Follower of India's most popular religion" .)
