The official opening ceremony of the 50th anniversary event of the Brazilian Association of Linguistics will be an outstanding moment. The opening ceremony will be attended by authorities who have contributed to the event. At the occasion, we will thank all the instances involved in the construction of the event. We will then have an opening conference with Maria Helena Mira Mateus: Linguistics, the science that identifies and envolves us. Then, we will pay tribute to the former presidents of Abralin. Finally, we will launch the book 50 Years of Abralin: Memories and Perspectives, which tells the trajectory of the Brazilian Association of Linguistics.
