Scar shown by the Devil? (3,7)
I believe the answer is:
old scratch
'devil?' is the definition.
(thesaurus)
'scar shown by the' is the wordplay.
I cannot really understand how this works, but
an anagram of 'scar' is 'scra' which is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for old scratch that I've seen before include "cause of small scar, perhaps" , "Diabolical character" .)
