Languages of South Sudan
In the state of Western Bahr el Ghazal, in its border region with the neighboring country of Sudan, there is an indeterminate number of Baggara Arabs (traditionally nomadic people) that resides either seasonally or permanently. Their language is Chadian Arabic and their traditional territories are in the southern portions of the Sudanese regions of Kurdufan and Darfur. In the capital, Juba, there are several thousand people who use an Arabic pidgin, Juba Arabic. Since South Sudan was part of Sudan for a century, some South Sudanese are conversant in either Sudanese Arabic or Modern Standard Arabic. Juba Arabic is a lingua franca in South Sudan.
