Impoverished neighbourhood preferred flat's interior (6)
I believe the answer is:
favela
'impoverished neighbourhood' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'preferred flat's interior' is the wordplay.
'preferred' becomes 'fave' (short for favourite).
'interior' says to take the centre.
The middle letters of 'flat' are 'la'.
'fave'+'la'='FAVELA'
Can you help me to learn more?
(Other definitions for favela that I've seen before include "Shanty town, especially in Brazil" , "(Brazilian) shack, shanty town; Alf, Eva (anag.)" , "Brazilian slum" , "Ramshackle town" , "Shantytown in Brazil" .)
