"Thank you and you're welcome."
Translation:Kirimvose se biarvose.
"You're welcome" in English is a reply to "Thank you" if you want to say something like "It was no problem" or "I am happy to have done that for you". It is a phrase that has (almost) nothing to do with "Welcome".
So, if someone says "Kirimvose" to you, you would probably answer with "Biarvose", but if a guest enters your house, you would say "Jiorna".
