Afitti (also known as Dinik, Ditti, or Unietti) is a language spoken on the eastern side of Jebel el-Dair, a solitary rock formation in the North Kordofan province of Sudan. Although the term 'Dinik' can be used to designate the language regardless of cultural affiliation, people in the villages of the region readily recognize the terms 'Ditti' and 'Afitti'. There are approximately 4,000 speakers of the Afitti language and its closest linguistic neighbor is the Nyimang language, spoken west of Jebel el-Dair in the Nuba Mountains of the North Kordofan province of Sudan.

Afitti is spoken primarily in Kundukur, Shakaro, and Kitra, at the foot of the Jebel ed-Dair and northwest of it; near Jebel Dambeir, Dambeir, and el-Hujeirat (Rilly 2010:182-183). There are about 4,000 speakers of two dialects, Ditti (spoken mainly in Kitra) and Afitti proper (spoken in the rest of the villages). However, the situation is complicated by extensive intermarriage.

The Afitti live to the east of Jebel el-Dair. They previously resided at the base of the mountain, but after World War I increasing numbers of cattle and overcrowding drove them down the mountain to the plain where they resettled on farms. As a result of these movements the towns of Kitra in the north, Kundukur in the east, and Sidra towards the south were established. Because of an increase in the number of cattle, a separate group was forced to settle at the foot of Jebel Dambir, further northeastwards. Cattle herders from Sidra settled to the southwest of Dambir and those from Kitra to the northeast. Today, the people of Kitra are known as “Ditti” while the others are known as "Afitti", but the dialects have only minor lexical differences between them.

When a drought struck the country in 1984, the majority of the cattle herders lost their livestock and became farmers; consequently, Afitti and Ditti speakers no longer herd cattle. In the 1950s, when Islam entered the area, the process of conversion began and today all speakers of Afitti are considered Muslim. Arabic has become the main language of communication, especially for the Afitti speakers; the local school also uses Arabic for teaching. The change of occupation for the cattle herders, the modernization in Sidra, and the overall dominance of Arabic have combined to reduce the overall importance of Afitti as well as decreasing speaker proficiency. Loanwords pervade the language, and it is only the Ditti who raise their children until school-going age without the use of Arabic.

The table below illustrates the vowels of Afitti; the symbols in parentheses represent prominent allophones of the phoneme beside which they appear.

Afitti has six vowels that have an allophonic variation that is mostly predicted by the syllable structure. Vowels are relatively short in Afitti with occasional lengthening occurring in stressed syllables. Furthermore, vowels are shorter in closed syllables than they are in open syllables. In closed syllables, vowels become open and sometimes centralized. The schwa, however, is always short and limited in distribution, never being found in word-final position. It remains short when the syllable is stressed and in such cases the consonant that follows it may be geminated.

Combinations of two vowels are common in Afitti and include combinations where the second vowel is schwa. There are no clear (level) diphthongs and the vowels are given individual tones that can be analyzed as part of different syllables. Sequences of three or more vowels were not found within the confines of one word.
