What it means
For yes/no questions about past actions or completed events, Vietnamese swaps the present có . . . không frame for đã . . . chưa. đã marks past/perfective; chưa at the end asks "yet?". Reply: Rồi, (đã) V rồi (yes — already done) OR Chưa, chưa V (no — not yet). CRITICAL: never reply with Không here — *Không, họ chưa làm xong is WRONG. Không is tense-blind in English ("no") but tense-bound in Vietnamese: không for present/future, chưa for past.
Câu hỏi yes/no về việc đã hoặc chưa hoàn thành dùng khung đã . . . chưa thay cho có . . . không. đã đánh dấu quá khứ; chưa ở cuối hỏi "đã ... chưa?". Đáp: Rồi, (đã) V rồi (đã làm) HOẶC Chưa, chưa V (chưa làm). KHÔNG được trả lời Không ở đây — phải là Chưa.
