Region of India (3)
I believe the answer is:
goa
'region of india' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for goa that I've seen before include "holiday destination in Asia" , "Indian Territory" , "Former Portuguese colony on the west coast of India" , "Indian state, former Portuguese colony" , "State of India, a former Portuguese colony" .)
