Etymology 3: Propitiation

This word comes from the late 14th century. Its origins are from the Latin
“propitiationem” (nom. “propitiation”) which basically means "an atonement." It also stems from the Latin “propitiare” which means, "render favorable," and from “propitious” meaning "favorable, gracious, kind." Its roots are pro- "forward" + petere "go to.” The earliest recorded form of the word is “propitiatorium,” or "the mercy seat, place of atonement" (c.1200), translating the Greek “hilasterion.”
