Get hot wandering around slum area? (6)
I believe the answer is:
ghetto
'slum area?' is the definition.
(I've seen this before)
'get hot wandering' is the wordplay.
'wandering' indicates anagramming the letters.
'get'+'hot'='gethot'
'gethot' with letters rearranged gives 'GHETTO'.
'around' acts as a link.
(Other definitions for ghetto that I've seen before include "run-down part of town" , "Former Jewish quarter" , "Slum area occupied by particular group" , "A poor quarter of a city" , "In the -- (Elvis Presley)" .)
