Supply drugs, not cocaine, to restore harmony amongst parties (7)
I believe the answer is:
mediate
'restore harmony amongst parties' is the definition.
I can't judge whether this definition defines the answer.
'supply drugs not cocaine' is the wordplay.
'supply drugs' becomes 'medicate' (I've seen this before).
'not' indicates named letters should be taken away.
'cocaine' becomes 'C' (drugs abbreviation).
'medicate' with 'c' taken away is 'MEDIATE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for mediate that I've seen before include "Arbitrate between parties in dispute" , "Help resolve a dispute" , "try to resolve dispute" , "Intervene, act as go-between" , "Intercede" .)
