Kako dobro možemo vzajemno råzuměti sę?

Our Vision
Every language has it’s roots that could lead to the future.
In today’s world, full of new opportunities, progress, great collective endeavors, and great divisions, our goal is to explore common linguistic features through pioneering scientific methods and to create practical tools for more effective language education and mutual communication in Europe and beyond.

Our Methods
Comparative Linguistics
We gather quality linguistic data about all the Slavic languages from native speakers and various other sources in order to compare their features and mutual intelligibility potential on various levels and combinations.
The Interslavic Language – Medžuslovjansky język
One of the naturalistic auxiliary linguistic tools we are experimentally developing in order to see the mutual intelligibility within one languge family at it’s fullest – without prior study! This allows us to compare the correlations between naturality, intelligibility and simplicity and gives better understanding of the living essence of the Slavic and human communication and linguistic heirtage in general on a level no simple dictionary can provide.
Education and Culture
Here we put our data and experience in practice. With the help of international cooperation we develop new methods of learning, language understanding, international cultural heirtage preservation and communication ready for use within Slavdom but also serving to clear the way for similar innovative research and work in other cultural and linguistic regions around the world.
