Brasília 2024

Upcoming Contest

Brasília 2024

Brasília (Brazil) has been chosen as the host of the 21st International Linguistics Olympiad on July 2024.

Important Dates

Requesting new working language*

Before Jan 31, 2024

  • A new working language means a language that was not present in the previous IOL. Please, note that countries can ask for any language. Asking for a particular language (e.g. English) does NOT give an advantage during the contest – all language versions are equal.

The list of the IOL 2023 working languages can be seen on the IOL 2023 working languages page. Please, make sure that you have read through the Working language(s) selection page carefully before requesting a new language.
