Bedouin Arabic[1] refers to a typological group of Arabic dialects historically linked to Bedouin tribes, that has spread among both nomadic and sedentary groups across the Arab World. The group of dialects originate from Arabian tribes in Najd and the Hejaz that have spread since the 10th century until modern day. Bedouin dialects vary by region and tribe, but they typically share a set of features which distinguish them from sedentary-type dialects in each region.
The term can be ambiguous, as it can refer to dialects of nomadic Bedouins, dialects of Bedouin-descended populations, or sedentary dialects that have been influenced by Bedouin dialects.
Background
The similarities between Bedouin dialects are due to their historical contact with one another, due to rapid population movements that quickly erase linguistic diversity.[2]
Preserving interdental consonants Ṯāʾ/θ/, Ḏāl/ð/, and Ẓāʾ /ðˤ/. Like in most other dialects, Ḍād and Ẓāʾ have merged, so Ḍād is also pronounced as /ðˤ/. Many sedentary dialects preserve them as well, while many pronounce them as /t/, /d/, and /dˤ/, respectively. In some sedentary dialects in Egypt and the Levant, interdental consonants in loans from Standard Arabic are often pronounced as /s/, /z/, and /zˤ/.
Preserving nunation as suffix -in, for example: bintin zēnah.
Distinguishing masculine and feminine plural pronouns -hum and -hun.
Internal passive verb forms, such as kutib (passive voice of katab). In sedentary dialects, prefixes such as in- (inkatab) and it- (itkatab) are used.
Eastern Bedouin features
Verbal suffix -ūn to mark plural subjects.
Palatalization of /g/ (qāf) and /k/ occurring before front vowels, with two realizations:
Northwest Arabian Arabic, a variety of Arabic spoken by Bedouins mostly in northwestern Saudi Arabia, southern Jordan, southern Israel, and eastern Egypt.
