Tradução - Turco-Português Br - Merhaba guzel turkce konusuyorsunuz. nerede ogrendiniz?

I'm not sure about "vocês falam", this one means :
Hello, you speak Turkish well. Where did you learn?
but I guess in a polite way

konuşuyorsunuz=vocês falam (it means ''you speak'' more than one person),konuşursun= você fala( it means ''you speak'' only one person).

Yes this is what I mean, I guess it's only one person but "sunuz" is used in a polite way.

no matter,''siniz'' and ''sunuz'' in turkish mean ''you'' in plural, vocês is used in plural form, brazilian portuguese has ''tu'' and ''você'' is used in singular when we talk to one person,both of them r used that s a personal choice when we talk.

I Know ''siniz'' and ''sunuz'' means you (plural) but I know it's also used as You singular in a polite way.
