Sudanese Arabic
In northern and central parts of Sudan, Sudanese colloquial Arabic has been influenced by the Nubian language, which in ancient times was the dominant language in Southern Egypt and Northern Sudan. Many of the agricultural and farming terms in Sudanese Arabic were adopted from Nubian.Because of the varying influence of local languages in different parts of Sudan, there is considerable regional variation in Arabic spoken throughout the country. Sudanese Arabic typically refers to Arabic spoken mostly in central parts of Sudan. The other most commonly mentioned derivative of Sudanese Arabic is Juba Arabic, a pidgin of Arabic spoken in South Sudan, which is much more heavily influenced by other local languages.
