Swimming in aid, new and exotic (6)
I believe the answer is:
'exotic' is the definition.
Although both the answer and definition are adjectives, I can't see how they can define each other.
'swimming in aid new' is the wordplay.
'swimming' indicates anagramming the letters.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'inaid' is an anagram of 'india'.
'and' is the link.
Can you help me to learn more?
(Other definitions for indian that I've seen before include "One from the sub-continent" , "Eg, native of Delhi" , "National" , "One type of elephant" , "American originally" .)
