Pacify, appease (7)
I believe the answer is:
placate
I believe this clue is a double definition.
'pacify' is the first definition.
(I know that pacify can be written as placate)
'appease' is the second definition.
(I know that appease can be written as placate)
(Other definitions for placate that I've seen before include "Calm, pacify, appease" , "Make less angry" , "Make calm, conciliate" , "Mollify, soothe anger" , "Mollify, appease" .)
