There is a new freely(!) available glossary of Old Uyghur that has been published:
Wilkens, Jens. 2021. Handwörterbuch des Altuigurischen: Altuigurisch – Deutsch – Türkisch / Eski Uygurcanın El Sözlüğü: Eski Uygurca – Almanca – Türkçe. Göttingen: Akademie der Wissenschaften zu Göttingen. https://doi.org/10.17875/gup2021-1590.
Accordingly, I have begun to add entries from this source and have added Old Uyghur as a new language. It’s tricky because Orkhon Turkic is already in the database, and not all sources clearly differentiate between the two. They do appear to be different, especially as Old Uyghur has clear influences from Chinese and Sanskrit and was affiliated with very large kingdoms. Orkhon, on the other hand, is a bit more limited and found mostly on stela in Mongolia. I may need to revisit this.
I’ve been occasionally working through the rest of Khorasani Turkic. It’s a bit of a mess. I’ve been very busy with work, so this project has become a low priority for the time. I’ve added the first 50 words from Old Uyghur and should have this completed sometime soon.
