The Sámi languages, all listed in UNESCO's Atlas of the World's Languages in Danger as endangered to various degrees, meet the various challenges they face according to the demographics of their speakers and the geographical conditions and ideological contexts in which they are spoken. The many efforts and initiatives taking place in Sámi communities indicate the vitality of these languages and their favorable development for the future. Such efforts also indicate that cultural workers, educators, and other community members engaged in the development and the transmission of languages to younger generations are central to this process. They sometimes fill a more important role than the legal and institutional structures that aim at promoting the Sámi languages. Collaboration between language communities in different countries of Sápmi is key to supporting revitalization. In this article, we provide examples of such efforts and initiatives and discuss the challenges to be addressed. We also emphasize the resilience of the Sámi languages—spoken in contemporary contexts, gaining value among the young generation, and taking on new domains.
