The Chinese word "失误" is formed by combining two characters: "失", which conveys the notion of losing or missing something, and "误", which denotes an error or mistake. Together, they create a compound word where the meanings merge to express the concept of a slip-up or fault, typically referring to an unintended mistake due to inattention or misjudgment, thus encapsulating the idea of an error that results from a lapse rather than intentional wrongdoing.
