About the Olympiad

The Online Olympiad in Linguistics was conceived as an annual competition that would allow secondary school students from all over the world to get closer to understanding the scientific beauty of language. It can also serve as practice before the (offline) International Linguistics Olympiad, which takes place every summer and brings together students from many countries. Unlike the IOL, however, the Online Olympiad is well suited for problems that involve real-time interaction and feature multimedia materials.

Each linguistics problem concerns a different language. Nevertheless, participation in the Olympiad does not require the student to have any prior knowledge of linguistics or languages. All the data necessary to solve the problem is contained in it, and it is up to the participant to obtain the solution by correctly putting the necessary pieces of information together.

The core of our team currently consists of several problem committee members of the Ukrainian Linguistics Olympiads and a few international volunteers. We have been organizing online contests for Ukrainian students since 2015, and we are excited to share this kind of experience with other nations.

If you have any questions, please contact us at .
