IPA: /ˌæntɪˈklaɪmæks/
KK: /ˈæntɪˌklaɪmæks/
A situation or event that is much less exciting or important than what was expected, often following something more impressive.
The movie built up to an exciting climax, but the ending felt like an anticlimax.
Anticlimax is formed from "anti-" (meaning against) and "climax" (from Greek "klimax", meaning ladder or a series of stages). The term describes a situation that goes against the expected climax, resulting in a disappointing or trivial conclusion instead of a dramatic one.
Think of 'against' ('anti-') the 'climax' or peak of a story — that's why an anticlimax is a letdown after building up to something exciting.
