Sudanese Arabic

Sudanese Arabic is the variety of Arabic spoken throughout Sudan and in parts of Eritrea. Some of the tribes in Sudan still have similar accents to the ones in Saudi Arabia.
History.
In 1889 the "Journal of the Royal Anthropological Institute" of Great Britain claimed that the Arabic spoken in Sudan was "a pure but archaic Arabic". The pronunciation of certain letters was like Hijazi, and not Egyptian, such as g being the pronunciation for the Arabic letter Qāf and J being the pronunciation for Jim.
Unique phonological characteristics.
Sudanese Arabic is similar to Egyptian Arabic. While it does not share some of the characteristic properties of northern Egyptian dialects (like that of Cairo), Sudanese Arabic is particularly close to central and southern Egyptian or Sa'idi Arabic. It is also closely related to Hejazi Arabic.
The Arabic letter ج maintains an archaic pronunciation in Sudanese (other dialects typically have , or , while Cairene Arabic has ).
Sudanese Arabic also maintains an archaic rendering of qaf as (Voiced uvular plosive) while Cairene Arabic (like some other modern Urban dialects) renders it as . The uvular rendering of qaf has been lost in most other Arabic dialects and is also considered a relic.
Also peculiar to Sudanese is the quality of the Arabic vowel transliterated as "u/ū"; this is usually transliterated as "o" in materials on Sudanese because the sound ranges from ~ rather than the typical ~.
In addition to differences in pronunciation, Sudanese Arabic also uses some different words when compared to Egyptian Arabic. For example, the interrogative pronoun "what" in Sudan is "shinu" rather than "eh" as in Egyptian Arabic.
Influence of Nubian languages.
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 northern and central Sudan. Many of the agricultural and farming terms in Sudanese Arabic were adopted from Nubian.
Regional variation.
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 northern and 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.
Greetings in Sudanese Arabic.
In northern Sudan, greetings are typically extended, and involve multiple questions about the other person's health, their family etc. When greeting an informal acquaintance, it is common to begin with the word "o", followed by the person's first name: "Ō, Khalafalla" or "Ō, kēf ya Khalafalla".
Formal greetings often begin with the universal "As-salām ˤalaykom" and the reply, "Wa ˤalaykom as-salām", an exchange common to Muslims everywhere. However, other greetings typical to Sudan include "Izzēyak" (to men) or " Izzēyik" (to women). A rather informal way to say "How are you", is "Inta shadīd? Inti shadīda?" "Are you well? (to a male and a female, respectively)", the response to which is usually "al-Hamdo lillāh" "Praise God" assuming you are indeed feeling well, "ma batal" "not bad" or "nosnos" "half-half)" if feeling only okay or "taˤban showayya" "a little tired" if not so well. Of course, there can be many other responses but these are used in everyday language.
Other everyday greetings include "kwayyis(a), alhamdulilah" "Good, thanks to allah", "Kēf al-usra?" "how is the family?" or "kēf al awlād?" "how are the children". For friends, the question "Kēf?" can also be formed using the person's first name, prefixed by "ya", for example; "kēf ya Yōsif?" "How are you, Joseph?". Another standard response in addition to "al-hamdu lillāh" is "Allāh ybarik fik" "God's blessing upon you". Additional greetings are appropriate for particular times and are standard in most varieties of Arabic, such as "Sabāh al-khēr? / Sabāh an-Nōr".
Sudanese that know each other well will often use many of these greetings together, sometimes repeating themselves. It is also common to shake hands on first meeting, sometimes simultaneously slapping or tapping each other on the left shoulder before the handshake (particularly for good friends). Handshakes in Sudan can often last as long as greetings. A handshake between well-acquainted Sudanese will often be preceded by raising one's right hand and touching each other's left shoulder simultaneously before engaging in the handshake, all while exchanging verbal greetings.
Assenting - saying yes.
The Sudanese Arabic word for "yes" depends on the tribe; "aye" is widely used, although "aywa" or "na‘am" are also commonly used.
