Cruel son after scrap, Welshman has claimed (11)
I believe the answer is:
remorseless
'cruel' is the definition.
(thesaurus)
'son after scrap welshman has claimed' is the wordplay.
I cannot quite see how this works, but
'son' could be 'ss' (I've seen this in other clues) and 'ss' is located in the answer.
'scrap' could be 'morsel' (I have seen 'Scrap of food ' mean 'morsel' so perhaps 'scrap' could also mean 'morsel') and 'morsel' is found within the answer.
The remaining letters 'ree' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for remorseless that I've seen before include "Lacking compassion" , "Savage" , "Inhumane" , "Without regret or guilt" , "Unrelenting" .)
