Dilling (also Delen, Warkimbe; autonym: Warki) is a Hill Nubian language spoken in the northwestern Nuba Mountains in the south of Sudan. It is spoken by around 11,000 people in the town of Dilling and surrounding hills, including Kudur. Ethnologue reports that Dilling is moribund, with only older adults speaking the language and not using it with their children. All speakers also use Sudanese Arabic. The Dilling call themselves Warki, while the Dilling speakers of Kudur call themselves Kwashe. Another ethnic minority that speak Dilling are the Debri people, a group of several thousands from South Kurdufan in Sudan
