Questions & Answers about dàjiā dōu dào le ma? wǒmen bā diǎn bàn chūfā ba.

What does the 都 in 大家都到了吗 add? Is it necessary?

• 都 (dōu) means “all,” distributing the statement over the whole group. It emphasizes that the question concerns every member: “Have they all arrived?”
• Without it, 大家到了吗？ still asks about everyone in context, but 都 makes the “all” explicit.
• Alternatives with a stronger “everyone is present” idea: 大家都到齐了吗？ or 人都到齐了吗？

Why is 了 used after 到 in 到了吗? What aspect is it?

• That 了 is the verb-suffix (perfective) 了, marking a completed event: “arrived (already/at some point).”
• Compare:
  • 到了 = arrived (this time; completed).
  • 到过 = have (ever) been to; experiential.
• Negation uses 没(有), not 不: 还没到, 没到 (not yet arrived). Saying 不到 here is wrong (it means “cannot reach/won’t reach”).

How do I answer this yes/no question naturally?

• Yes: 都到了。/ 都到齐了。/ 到了。
• No: 还没(到)。/ 还差两个人。/ 还有几个在路上。
• Elliptical A–N answers are common: 到了 / 还没.

Can I say 到齐 instead of 到? What’s the nuance?
