Man from Dulwich approached (4)
I believe the answer is:
chap
'man' is the definition.
(I've seen this in other clues)
'from dulwich approached' is the wordplay.
'from' indicates a hidden word.
'CHAP' is hidden in the letters of 'dulwich approached'.
(Other definitions for chap that I've seen before include "Split in skin" , "Skin crack due to cold - bloke" , "Man, sore patch" , "Bloke, fellow" , "Fish" .)
