2016 Olympics city (3)
I believe the answer is:
rio
'2016 olympics city' 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 "Location of next Olympic Games, in short" , "old capital" , "A Mexican river, may be grande" , "Spanish word for river" , "Brazilian city and port" .)
