Questions & Answers about Đừng hại người.
Đừng is used to make a negative command or negative request. It means something like don’t in English.
So the pattern is:
đừng + verb
Examples:
- Đừng nói. = Don’t speak.
- Đừng đi. = Don’t go.
- Đừng hại người. = Don’t harm people / others.
It is one of the most common ways to tell someone not to do something.
Because không usually means not in statements, not in commands.
Compare:
- Tôi không biết. = I do not know.
- Anh ấy không đi. = He is not going.
But if you want to tell someone don’t do X, Vietnamese normally uses đừng, not không:
- Đừng đi. = Don’t go.
- Đừng hại người. = Don’t harm others.
So for negative imperatives, đừng is the natural choice.
