Acknowledgments

We express our sincere gratitude to the Department of Linguistics and Basque Studies and the University of the Basque Country for their invaluable institutional support. We also warmly thank the Araba Provincial Council (Department of Equality, Basque Language, and Governance) and Vital Fundazioa for their generous financial assistance.

We are especially grateful to our colleagues Gidor Bilbao for facilitating our connection with the Araba Provincial Council, Iván Igartua for his support in securing assistance from Vital Fundazioa, and Dorota Krajewska for her dedicated help in preparing the announcement posters and the abstract booklet. We also extend our heartfelt thanks to Pepe Sainz Varela, head of the Archive of Araba, for kindly providing us with the booklets dedicated to the Reja.
