Former Portuguese colony on India's west coast (3)
I believe the answer is:
goa
'former portuguese colony on india's west coast' 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 holiday destination" , "Indian district" , "Indian state, former Portuguese colony" , "part of subcontinent" .)
