Man snubbed sullen young woman (6)
I believe the answer is:
dougal
'man snubbed sullen young woman' is the definition.
I can't tell whether this definition defines the answer.
'snubbed sullen young woman' is the wordplay.
'snubbed' means to remove the last letter (could historically mean cutting the end off).
'sullen' becomes 'dour' (synonyms).
'young woman' becomes 'gal' (synonyms).
'dour' with its final letter taken off is 'dou'.
'dou'+'gal'='DOUGAL'
Can you help me to learn more?
(Another definition for dougal that I've seen is " Roundabout barker (not really)".)
