‘丢掉’ is a compound verb meaning 'to throw away' or 'to discard' — literally, 'to lose and drop (away)'. The first character 丢 (diū) means 'to lose' or 'to misplace', while the second character 掉 (diào) adds a sense of removal, separation, or falling away; together, they emphasize intentional disposal rather than accidental loss. This verb is commonly used in everyday contexts when referring to getting rid of unwanted physical objects — such as old clothes, broken items, or food waste.

It’s a transitive verb requiring a direct object (e.g., 丢掉垃圾, 丢掉旧书), and often implies finality or deliberate action — unlike 丢 (diū) alone, which can mean 'to lose accidentally'. It carries a neutral-to-slightly-negative tone depending on context: discarding trash is practical, but discarding opportunities or relationships may sound regretful or careless. It’s widely used in spoken and written Mandarin, especially in instructions, household routines, and environmental discussions.
