Logorik language
Logorik, Subori, or Saburi is a (critically) endangered language spoken in Eastern Sudan and Western Chad. General information 
It is a part of the Nilo-Saharan group and the subcategory of the Eastern Daju languages. It is spoken by the Subori people in the Nuba Mountains and South Kordofan. Meinhof claims, that there are hardly any similarities between this language and other Kordofan languages vocabulary-wise. At the same time, the Logorik-speaking community is overwhelmingly bilingual; other dominating languages being, among others, Arabic, (due to the Arabic migration in the region). This causes a high percentage of loanwords and grammatical borrowings (mostly Arabic) in the Logorik language. Phonetics
