The Chinese word **减掉** is formed through a standard grammatical construction where the core verb **减** (jiǎn, meaning "to reduce" or "to subtract") is combined with the resultative complement **掉** (diào), which indicates a sense of "off," "away," or completion of the action. Thus, **减掉** literally means "to reduce away" or "to subtract and remove," conveying the complete action of eliminating a quantity from something, as in "减掉十公斤" (lose ten kilograms). This verb-complement structure is common in Mandarin to specify the result or direction of an action.
