mollification (n.)

late 14c., mollifien, "to soften (a substance)," from Old French mollifier or directly from Late Latin mollificare "make soft, mollify" from mollificus "softening," from Latin mollis "soft" (from PIE root *mel- (1) "soft") + combining form of facere "to make, to do" (from PIE root *dhe- "to set, put"). Transferred sense of "soften in temper, appease, pacify" is recorded from early 15c. Related: Mollified; mollifying.
