Thank you to Glenn Pittsford for this interesting link:

Presentation at the University of Economics in Bratislava in 2019

It is about the Sorbs and the Sorbian language.

Glenn's comments:

We went right past Bratislava and Slovakia on our Danube cruise but we did not get to stop there- I sure wanted to.

Weldon, it looks to me like this guy is basically telling us what you told us in your Wendish class in Giddings, except it's in Wendish I guess. The words sound and look familiar, and the pictures verify that he is talking about "us". Correct? Have you seen this one before? I know he is talking ABOUT the Wends (Sorbs) and showing us some of the words and all like you did. I think he is maybe basically talking in the language of Slovakia, not sure.

I never knew what a polyglot was but I have looked it up: "knowing or using several languages". That's you. Probably no word for it in upper Sorbian I guess.
