Teaching is the main or even only way to pass on ancestral languages when intergenerational language transmission no longer takes place. The main reason for the interruption of natural language transmission is an increasing weakening of community bonds due to intermarriage, migration, and mobility. The formal or informal teaching of ancestral languages is therefore at the core of language revival and language revitalization movements. The article reviews favorable conditions and supportive factors for the teaching of ancestral languages from different parts of the world, and highlights the important role of dedicated community members in these endeavors.
