propitiate

Like its synonym "appease," propitiate means "to ease the anger or disturbance of," but there are subtle differences between the two terms as well. "Appease" usually implies quieting insistent demands by making concessions, whereas "propitiate" tends to suggest averting the anger or malevolence of a superior being. In fact, "propitiate" often occurs - as in our first example sentence - in contexts involving deities, spirits, or other preternatural forces. You might "appease" your hunger, but to speak more colorfully, you could "propitiate the gods of hunger."
