In this book, Ghil'ad Zuckermann introduces revivalistics, a new trans-disciplinary field of enquiry surrounding language reclamation, revitalization, and reinvigoration. Applying lessons from the Hebrew revival of the late nineteenth and early twentieth centuries to contemporary endangered languages, Zuckermann takes readers along a fascinating and multifaceted journey into language revival and provides new insights into language genesis. Beginning with a critical analysis of Israeli-the language resulting from the Hebrew revival-Zuckermann's radical theory contradicts conventional accounts of the Hebrew revival and challenges the family tree model of historical linguistics. Revivalistics demonstrates how grammatical cross-fertilization with the revivalists' mother tongues is inevitable in the case of successful 'revival languages.' The second part of the book then applies these lessons from the Israeli language to revival movements in Australia and globally, describing the 'why' and 'how' of revivalistics. With examples from the Barngarla Aboriginal language of South Australia, Zuckermann proposes ethical, aesthetic, and utilitarian reasons for language revival and offers practical methods for reviving languages. Based on years of the author's research, fieldwork, and personal experience with language revivals all over the globe, Revivalistics offers ground-breaking theoretical and pragmatic contributions to the field of language reclamation, revitalization, and reinvigoration.
