Port found in poor Spanish-speaking area with no bar (3)
I believe the answer is:
rio
'port' is the definition.
(Rio de Janeiro is a port)
'spanish-speaking area with no bar' is the wordplay.
'spanish-speaking area' becomes 'barrio' (I've seen this before).
'with no' suggests deleting specific letters.
'barrio' with 'bar' taken out is 'RIO'.
'found in poor' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for rio that I've seen before include "A Mexican river - like Grande" , "Erstwhile home of Biggs" , "Port, -- de Janeiro" , "... Grande, ... de Janeiro" , "Location of next Olympic Games, in short" .)
