Old Tibetan (OT) Dictionary is an online reference work intended to help scholars to read, analyse, and translate Old Tibetan documents in their lexical specificity.

The data presented in the OT dictionary comes from linguistic analyses of the OT text corpus and is restricted to the information found in the heretofore scrutinised texts.

The Dictionary has been developed within the projects Alttibetische Annalen. Eine umfassende Textgrammatik. Teil I & II (BI 1953/1-1 & BI 1953/1-2) financed by the Deutsche Forschungsgemeinschaft in years 2017-2020 & 2020-2022.

The dictionary is still under construction
