Definitions

1. A disappointing or underwhelming conclusion that fails to meet the expectations created by preceding events or buildup

Etymology: The most striking thing about "anticlimax" is how precisely its parts were built to oppose each other. "Climax" comes from Greek "klimax," meaning "ladder" or "staircase," and in rhetoric it named the rising arrangement of a sentence or argument, each step stronger than the last. Adding the Greek prefix "anti-," meaning "against" or "opposite," produced a word for the reverse: a fall rather than a rise, the point where a build-up collapses into something flat or trivial. The word is a compound formed in English from "anti-" and "climax," so its meaning is transparent once the parts are known. Its use as a term for a disappointing ending, rather than a rhetorical device, is the sense most readers now encounter, and it grew naturally out of the staircase image: the expected step up never arrives.
