Calm down ancient cuts and get revenge (6,3,6)
I believe the answer is:
settle old scores
'get revenge' is the definition.
(I've seen this in another clue)
'calm down ancient cuts' is the wordplay.
I cannot quite understand how this works, but
'calm' could be 'settle' (I've seen this in another clue) and 'settle' is found within the answer.
'down' could be 'd' and 'd' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for settle old scores that I've seen before include "Deal with historical complaints" , "Get even" .)
