The eleventh episode of our Window to the World series takes us to the western Slovak town of Leopoldov and to the small village of Heinersbrück in eastern Germany. In this instalment, our colleagues Michal Herceg and Juraj Pavlovič explore how this rather unusual partnership began — and how cooperation between the two communities has continued to grow over the years, building lasting ties across borders. And later on, in our Slovak Sound Check segment, you’ll have a chance to strengthen your language skills as we take a closer look at possessive pronouns — an essential part of everyday Slovak.
