Hello Grambank! A new typological database of 2,467 language varieties
Grambank has been many years in the making, and is now publically available!
The team coded 195 features for 2,467 language varieties, and made this data publically available as part of the Cross-Linguistic Linked Data-project (CLLD). They plan to continue to release new versions with new languages and features in the future.
Below are maps for two features I’ve selected that show very different distribution across the world’s languages. The first map codes for whether there are prepositions (in yellow), and we can see really clear clustering of them in Europe, South East Asia and Africa. Languages without prepositions might have postpostions or use some other strategy. The second map shows languages with an existential verb (e.g. there *is* an existential verb, in yellow), we see a different distribution.
What makes Grambank particularly interesting as a user is that there is extensive public documentation of processes and terminology on a companion GitHub site. They also have been very systematic selecting values and coding for them for all the sources that they have. This is a different approach to that taken for the World Atlas of Linguistic Structures (WALS), which has been the go-to resource for the last two decades. In WALS a single author would collate information on a sample of languages for a feature they were interested in, while in Grambank a single coder would add information on all 195 features for a single grammar they were entering data for.
I’m very happy that Lamjung Yolmo is included in the set of languages in Grambank, with coding values taken from my 2016 grammar of the language. Thanks to the transparent approach to coding in this project, you can not only see the values that the coding team assigned, but the pages of the reference work that the information was sourced from.
