Country to support province after reverse (5)
I believe the answer is:
Here is my best explanation:
'country' is the definition.
(India is an example)
'support province after reverse' is the subsidiary indication.
'support' becomes 'aid' (aiding is a kind of supporting).
'province' becomes 'ni' (I've seen this in other clues).
'after' means one lot of letters go next to another.
'reverse' shows that the letters should be reversed in order.
'aidni' back-to-front is 'india'.
'to' is the link.
(Other definitions for india that I've seen before include "Kiss; quarter of a bushel", "Large subcontinent of Asia", "Populous nation", "Country of the Ganges", "In aid, strangely, of the country", "The country", "part of Asia", "Eastern region", ""Bharat", locally" and "Code for the letter I".)
