Etymology

The word "disappointed" originated in the late 15th century, combining "dis-" (expressing reversal) and "appoint" (to arrange or assign). Originally, it meant "to remove from office," but by the 16th century, it evolved to mean "to fail to fulfill expectations," reflecting the emotional sense we use today. The logic follows: if something is "not arranged as hoped," it leads to sadness or frustration.
