The word "anticlimax" combines the Greek prefix "anti-" (meaning "against" or "opposite") with "climax" (from Greek "klimax," meaning "ladder" or "peak"). Originally used in rhetoric to describe a sudden shift from a lofty idea to a trivial one, it evolved to signify any letdown after heightened expectations. The morphemes preserve their original spelling and meaning, making the word’s structure logical and memorable.
