how do you say, how are you today... in yugoslavian.?

Answer 1

there are two ways to say that:

one is informal - "kako si danas?"
and the other is formal - "kako ste danas?"

and the person would probably say "dobro sam, hvala" (I'm fine thank you)

note: i is pronounced like in sit and e like in set.

and of course, I must stress that there is no yugoslavian language. What I wrote is in Serbian and it's the same in Croatian.

Answer 2

How are you today? --> Kako si danas?
You can also just say "Kako si?".
"i" is pronounced like "ee".
