Advances in the Historical Linguistics of Signed Languages

ABSTRACT Scholarship in the field of sign historical linguistics has made important progress in recent years. Here we survey this progress in three areas of research that have received the most attention to date, namely, (i) qualitative approaches to understanding the typical pathways of diachronic change in signed languages, (ii) quantitative approaches to signed language classification, and (iii) archival approaches to historical sociolinguistic research on signing communities and their languages. We also discuss how early work on sign historical linguistics has shaped the field's current questions and approaches, and we look forward to future advances that can tap into underutilized sources of historical video data on signed languages.
