Man of Dutch appearance (4)
I believe the answer is:
chap
'man' is the definition.
(term for a man)
'of dutch appearance' is the wordplay.
'of' indicates the answer is hidden within the clue.
'CHAP' can be found hidden inside 'dutch appearance'.
(Other definitions for chap that I've seen before include "Sore; cheek; man" , "(Of skin) become sore" , "Fellow; sore skin area" , "Skin crack due to cold - bloke" , "Fish" .)
