Linguistic watersheds: a model for understanding variation among the Tibetic languages

Abstract

This study applies the observation of alignment between geographical watersheds and linguistic groupings to the Tibetan Plateau and the Himalayas. Tournadre (2014) estimates 220 Tibetic language varieties in 25 major groupings, sharing a common linguistic ancestry. Typological groupings can be readily identified through mapping human settlements to watersheds. For areas that have yet to be researched, consistent hypotheses for typological groupings can be arrived at. Next to explaining anomalous data within a particular area or how certain linguistic features spread, a watershed-based map identifies possible linguistic areas to be researched. The concept is applied in detail to the watersheds and languages of Bhutan and then expanded out to the broader Tibetan region. Show more
