Placate with concessions (7)
I believe the answer is:
appease
'placate with concessions' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for appease that I've seen before include "Satisfy demands by making concessions" , "Calm, pacify, placate" , "Placate by making concessions" , "Mollify by making concession" , "be satisfying" .)
