Cursed mother to Scots hooligan (6)
I believe the answer is:
damned
'cursed' is the definition.
(synonyms)
'mother to scots hooligan' is the wordplay.
'mother' becomes 'dam' (female parent of an animal).
'to scots hooligan' becomes 'ned' (I can't explain this - if you can you should give a lot more credence to this answer).
'dam'+'ned'='DAMNED'
Can you help me to learn more?
(Other definitions for damned that I've seen before include "Mad Ned was doomed" , "Consigned to hell or perdition" , "Abominable" , "Cursed" , "Consigned to everlasting punishment" .)
