‘删掉’ (shān diào) is a common colloquial verb meaning 'to delete' — specifically, to remove something completely and permanently, with emphasis on the completion of the action. The first character 删 (shān) means 'to delete' or 'to strike out', while the second character 掉 (diào) is a resultative complement indicating that the object has been removed from its original state or location. Together, they convey a sense of finality: not just starting to delete, but successfully erasing or eliminating something.

This word is widely used in digital contexts (e.g., deleting messages, files, or social media posts), but also applies to physical actions like crossing out text or removing an item from a list. It’s more informal and action-oriented than formal alternatives like 删除 (shānchú). Native speakers often use it in spoken Mandarin and casual writing — especially when giving instructions or describing quick, decisive removal.
