The Belarusian language is officially at a dangerous stage, where there are not many native speakers left, and just a couple of centuries ago it was one of the main European languages. Duolingo, as one of the most popular and frequently used language learning apps, can make a huge contribution not only to one country but also to the world's heritage. In addition, after Russia’s full-scale invasion of Ukraine, many Belarusians realized the importance of national identity, including at least partial use of the Belarusian language. But under dictatorship, this is not only difficult, but can also be dangerous, since the Belarusian language shows disagreement with today's dictatorship policies of Russification. People are deprived of the opportunity to learn their own language, so the safest and most affordable way may be to use an online language learning app. In addition, Belarusians show their commitment to European values ​​and better availability of the Belarusian language for learning can help in making the Belarusian language more accessible to foreigners.
