Can anyone tell me how to say these phrases in Yugoslavian?

1) beautiful Princess

2) I am forever yours

3) I would do anything for you


Thank you all for your help.

Maybe someone can translate these into Croatian or Serberian, since these are former Yugoslavia?

Does anyone know the Croatian translation for these?

Well in croatian it would be...

Beautiful princess - predivna princezo

I am forever yours - zauvjek sam tvoj ( boy to girl )
- zauvjek sam tvoja ( girl to boy )

I would do anything for you - sve bih ucinio za tebe ( boy to girl )
- sve bih ucinila za tebe ( girl to boy )

I serbian is a little bit different but she/he will understad this .

There are no grammatical differences between Serbian and Croatian languages. Just some words that are said a little bit different. That difference is as same as difference between British and American english.
