Disappointment is the unhappy feeling you get when things don’t turn out as well as you wanted. It can be about events, people, or even yourself.
From 'disappoint' plus the noun suffix '-ment', from Old French and ultimately from Latin ideas of 'depriving of an appointment or arrangement'. It shifted from a practical sense of plans failing to an emotional one.
Disappointment is like emotional whiplash between 'what I pictured' and 'what actually happened'. The bigger the gap, the sharper the sting—so managing expectations is secretly a mental health skill.
