That’s great. I thought that would likely be the case - thanks for confirming.

When to use 对 and 对不对
# When to use 对 and 对不对

(Asked by: username_0 on 2024-04-04)

So firstly I must apologise as I am about two weeks into a Duolingo course - so I would say my understanding of the language is near enough 0.

However, I wanted to ask if someone could clarify some examples of when you would use **对** and **对不对**.

It is my understanding that they both mean the same thing, is one more formal than the other?

E.g. **对我是老师！** and **你是老师，对不对？**

Could you also say **对不对我是老师** or is that now becoming incorrect?

(Apologies if I am missing any grammar!)

"对" is used in reply confirming something is right/correct = Yes, it is correct.

"对不对" is used in inquiry = correct or incorrect?

* 你是老师，对不对？- You are a teacher, correct (or incorrect)?
* 对, 我是老师 - Correct, I'm a teacher.

你是老师，对吗？is roughly equivalent to 你是老师，对不对？
