What is another word for letdown?
Pronunciation: [lˈɛtda͡ʊn] (IPA) 
When we face a disappointment or a feeling of defeat, we often call it a letdown. However, there are several other synonyms that can be used to express the same sentiment, including disappointment, setback, failure, disillusionment, frustration, and discouragement. Disillusionment often refers to a case where one's expectation didn't match up to reality. Setback denotes a temporary obstacle that causes a decrease in progress. Frustration is frequently used to describe a feeling of powerlessness or inability to achieve one's goals. Failure, on the other hand, typically suggests a lack of success, while discouragement implies a sense of disheartenment. All these words help to describe that feeling when things don't go as planned.
