bust (1)
1691, "sculpture of upper torso and head," from Fr. buste, from It. busto "upper body," from L. bustum "funeral monument, tomb," originally "funeral pyre," perhaps shortened from ambustum, neut. of ambustus "burned around," pp. of amburere "burn around, scorch," from ambi- "around" + urere "to burn." Sense development in It. probably from Etruscan custom of keeping dead person's ashes in urn shaped like the person when alive. Meaning "bosom" is 1819; busty is first attested 1944.
