A sound way to put things right (5)
I believe the answer is:
atone
'right' is the definition.
(I know that atone is a type of right)
'a sound' is the wordplay.
'sound' becomes 'tone' (tone is a kind of sound).
'a'+'tone'='ATONE'
'way to put things' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for atone that I've seen before include "Make reparation for a misdeed" , "Adopt a cause" , "Make amends, being at one" , "Make up, compensate (for)" , "Make good" .)
