Brazilian slum (6)
I believe the answer is:
favela
'brazilian slum' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for favela that I've seen before include "Shanty town, especially in Brazil" , "Brazilian slum" , "Ramshackle town" , "(Brazilian) shack, shanty town; Alf, Eva (anag.)" , "Shantytown in Brazil" .)
