Char going through housing estate (5)
I believe the answer is:
singe
'char' is the definition.
(I know that singe is a more specific form of the action char)
'going through housing estate' is the wordplay.
'going through' indicates the answer is hidden within the clue.
'SINGE' can be found hidden inside 'housing estate'.
(Other definitions for singe that I've seen before include "Lightly burn" , "Char, scorch" , "Burn superficially" , "Burn the ends or edges of" , "Scorch lightly" .)
