2016 Olympics host (3)
I believe the answer is:
rio
'2016 olympics host' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rio that I've seen before include "place of carnival" , "Location of next Olympic Games, in short" , "(Golfer) in the sand" , "... Grande, ... de Janeiro" , "Erstwhile home of Biggs" .)
