What does disappointment mean?
Disappointment is the feeling of sadness, regret, or dissatisfaction that comes when our hopes, plans, or expectations are not met. Whether it is missing out on a long-awaited event, watching a promising project fall short, or realizing that something we anticipated simply did not happen, this word names one of the most universal human emotions. Beyond the internal feeling, 'disappointment' also refers to the external cause of that feeling — a person, performance, or outcome that fails to deliver what was hoped for. The word carries no strong regional variation and is equally at home in casual conversation and formal writing, often appearing in fixed phrases such as 'to her great disappointment' or 'a bitter disappointment'. Its grammatical family is rich: as a verb it is 'disappoint', and its adjectives 'disappointed' (describing the person who feels it) and 'disappointing' (describing the thing that causes it) are among the most frequently used forms in everyday English. Understanding this distinction helps writers choose precisely between describing the experiencer and the source of the emotion.

Etymology of disappointment
'Disappointment' derives from the verb 'disappoint', formed from the prefix 'dis-' (meaning 'away' or 'apart') combined with 'appoint', which itself traces back through Old French 'apointer' to the Latin 'punctum', meaning 'point'. In earlier usage, to disappoint someone could mean to remove them from an appointment or office — hence the literal sense of being 'un-pointed' or deprived of an expected position. The word has been used in English since at least the early modern period, with the emotional sense of unfulfilled expectation becoming dominant over time. Cognates sharing this Latin root include 'point', 'punctual', and 'appointment'.
