Key research themes
1. How did Old Tibetan phonology evolve into modern Amdo Tibetan dialects, especially regarding syllable rhymes?
This research area focuses on the diachronic phonological changes from Old Tibetan to present-day Amdo Tibetan dialects. Understanding vowel and consonant rhyme evolution sheds light on the linguistic history of the Tibetan language family and aids in reconstructing earlier phonological systems. It also clarifies the presence or loss of phonemic features such as vowel length.
2. What morphosyntactic influences did Old Tibetan extract on neighboring non-Tibetic languages in the Amdo Sprachbund?
Research on the Amdo Sprachbund investigates how morphosyntactic features of Tibetan, especially from Old Tibetan and its Amdo dialects, have been transferred into unrelated Turkic (Salar) and Sinitic (Wutun) languages under prolonged language contact. Understanding these structural borrowings informs theories of linguistic convergence and contact-induced grammatical change in South-Central Asia.
3. How do Old Tibetan manuscripts and grammatical texts contribute to our understanding of Old Tibetan linguistic structure and ritual practice?
This research theme covers the philological and linguistic examination of Old Tibetan manuscripts—both grammatical treatises and ritual texts—to reconstruct the language's syntax, morphology, grammatical terminology, and cultural context. It includes the corpus-building efforts for Tibetan grammatical works and detailed studies of liturgies that connect Old Tibetan religious practice with canonical traditions, which enrich the linguistic and cultural historiography of Tibetan.
