The Magic Word Ạ | Learn Vietnamese with TVO

Thank you for uploading, I am studying with you.

Cam ơn.
Tối tiền một giá.
I think I said that right.
I speak a bit and write.

what's the right order to follow in order to understand very well the lectures? I followed pretty well the first part of this one, but when it comes to the exercise there were a lot of words that I cant understand

This is such a useful and important lesson, thank you. I feel bad now for never having used ạ in all the conversations I've had with my neighbours!

Since I am a lot older than you, could you have said 'tam biet a' at the end ?

I love this series so much! THANK YOU :)

What's the difference (if any) between "ạ̣" and "vậy"--in terms of adding one at the end of a sentence, rather than the other?  My impression is that "vậy" is a particle(?), but can it serve as a term of respect also?

Would it be weird if you use “ạ” to someone similar age with you or someone you just don’t know a lot? Just to be respectful?

(Y)

is ạ similar or related to ₫ạ in any way?

What about à?
