I believe the answer is:
'asian' is the definition.
(I know that Indian is a type of asian)
This is all the clue.
(Other definitions for indian that I've seen before include "This summer may happen in late autumn" , "Relating to native of Bombay, say" , "Club, summer or rope-trick" , "Nationality of Salman Rushdie" , "Relating to Asian subcontinent" .)
