Questions & Answers about Bạn đã trả lời email của tôi chưa?
This is a very common Vietnamese pattern for asking whether something has happened yet.
- đã marks that the speaker is talking about a completed action or a past/completed event.
- chưa at the end turns it into a “yet?” / “have you...?” type of question.
So:
- Bạn đã trả lời email của tôi chưa? = Have you replied to my email yet?
This pattern is extremely common:
- Bạn ăn cơm chưa? = Have you eaten yet?
- Anh đến chưa? = Have you arrived yet?
In casual speech, sometimes đã may be omitted if the meaning is still clear, but đã ... chưa? is a very standard and natural structure.
