The Chinese word "擦掉" (cā diào) is a verb-result compound formed by combining the verb "擦" (cā), meaning "to wipe" or "to rub," with the resultative complement "掉" (diào), which indicates a successful completion or removal of something, often translating to "off" or "away." Together, the compound semantically conveys the action of wiping *and* its successful result, meaning "to wipe off" or "to erase," where the initial action leads to the object being removed or cleaned away. This structure is common in Mandarin for creating precise verbs that specify both an action and its outcome.
