Tenement locale (4)
I believe the answer is:
slum
'tenement locale' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slum that I've seen before include "Squalid, overcrowded dwelling" , "Ghetto" , "Area of poor housing" , "Over-crowded run-down city area" , "Squalid neighbourhood" .)
