For those who are still learning Viet phonology (as I) - Kh-sound is IPA [x] - like ch in German doch, or ch in Cymraeg chwech.
This sounds very much like the Chinese "空, " meaning empty or nothing
Không is a loanword from Chinese 空.
I've heard this word pronounced two different ways. Is this a northern vs southern accent difference?
The pronunciation of user "soixsauce" here differs from the others. Those are the two I've heard.
I think soixsauce pronounces it with a southern accent, thats exactly the same way I've heard it.
I put "does not" here and it marked me incorrect but corrected me with "do not" doesn't make sense to me please explain
Your answer is also correct in your case. For my case no = không .
You can hit the flag symbol to report that your answer is also correct
No this is the imperative, so in English that can only be "No!" or "Do not!" When used in a sentence, if the subject is third person singular (he, she or it) than it could be "does not".
This whole lesson appears to have no audio. Other lessons do, so it's not a technical problem on my computer.
