Burns part of housing estate (6)
I believe the answer is:
singes
'burns' is the definition.
(singing is a kind of burning)
'part of housing estate' is the wordplay.
'part of' indicates a hidden word.
'SINGES' is hidden within 'housing estate'.
(Other definitions for singes that I've seen before include "burn-marks" , "Burns superficially" , "Burns slightly, maybe while ironing" , "Burns lightly" , "Scorches on the surface" .)
