The Land Dayak languages are a group of dozen or so languages spoken in by the Bidayuh peoples of Borneo. Some are closely related, but the unity of Land Dayak as a group is dubious.

The languages/dialects are Ahe, Bekati’, Biatah, Benyadu’, Djongkang, Lara’, Nyadu, Ribun, Sanggau, Semandang, Bukar Sadong, Jagoi, Sara, Tringgus, Kembayan, and several others.

However, a 2008 analysis of the Austronesian Basic Vocabulary Database^[1] found that the Bekati’ and Jagoi languages (the two Land Dayak languages included in the analysis) were no more closely related to each other than the were to the Barito and North Sarawakan languages. Indeed, the calculated confidence that any of these languages formed a valid unit was only 56%.
