Revivalistics is a new comparative, global, trans-disciplinary field of enquiry studying comparatively and systematically the universal constraints and global mechanisms on the one hand, and particularistic peculiarities and cultural relativist idiosyncrasies on the other, apparent in linguistic reclamation, revitalization and reinvigoration across various sociological backgrounds, all over the globe. This article introduces revivalistics, and postulates heritage language as core to people’s wellbeing, spirituality and happiness. Hallett, Chandler and Lalonde reported a clear correlation between lack of conversational knowledge in the native tongue and youth suicide. However, so far there has been no systematic study of a correlation in the other direction, i.e. the impact of language revival on empowered wellbeing, improved mental health and reduction in suicide. This is partly because language reclamation is still rare. This article hypothesizes that just as language loss increases suicide rate, language gain reduces suicide rate, improves wellbeing and increases spirituality. The article focuses on the Barngarla Aboriginal language of Eyre Peninsula, South Australia. Barngarla became a Dreaming, Sleeping Beauty tongue in the 1960s. It belongs to the Thura-Yura language group, which is part of the Pama-Nyungan language family, which includes 306 out of 400 Aboriginal languages in Australia, and whose name is a merism derived from the two end-points of the range: the Pama languages of northeast Australia (where the word for ‘man’ is ‘pama’) and the Nyungan languages of southwest Australia (where the word for ‘man’ is ‘nyunga’). The author of this article has been facilitating the Barngarla reclamation since 14 September 2011.
