Spanish for "river" (3)
I believe the answer is:

This is all the clue.
(Other definitions for rio that I've seen before include "A Mexican river - like Grande" , "The ... Grande borders Texas and Mexico" , "Manchester United player in South American city, in short?" , "A Mexican river, may be grande" , "Port, -- de Janeiro" .)
