The word "挫折感" is formed by combining the character 挫, meaning to frustrate or defeat, with 折, meaning to break or bend, creating the compound 挫折 which signifies a setback or frustration; this is then combined with 感, meaning feeling or emotion, to denote the specific sensation or emotional experience of encountering such setbacks, resulting in a term that translates to a sense of frustration or feeling of defeat.
