Of the sub-continent (6)
I believe the answer is:
indian
'of the sub-continent' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for indian that I've seen before include "Native of North America" , "Nationality of Salman Rushdie" , "This summer may happen in late autumn" , "National" , "IDA inn provided for this nationality" .)
