You might have spent it in India (5)
I believe the answer is:
rupee
'india' is the definition.
I know that 'india' relates to this answer. I also know that both the answer and definition are singular nouns
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rupee that I've seen before include "cash" , "Indian rhino" , "Indian bread" , "foreign currency" , "Currency of the subcontinent" .)
