In this introduction, we offer an overview of language revitalisation (LR) as a transdisciplinary field and its connections to related disciplines. We outline its evolution from its origins, current directions, and possible future moves. In the last section, we introduce each of the articles in the special issue as they relate to three current developments in the field of LR: the role of the researcher in LR, the causes of language endangerment, and the impact of globalisation.
