Demographics of the Arab League
On the other hand, Arabic is divided into over 27 dialects. Almost every Arab state has at least one local dialect of its own. they can be divided into 5 major branches, the Peninsula Arabic, which is the Arabic used in the Arabian peninsula, with around 9 main dialects, Arabic of the Nile Valley, which includes the Masri, Saedi, Sudanese and Chadic Arabic, the Arabic of the Fertile Crescent, which includes the Bedawi, Levant Arabic, Iraqi Arabic and North Mesopotamian Arabic, the Magharbi Arabic, which includes the Dialects used in Mauritania, Morocco, Libya, Algeria and Tunisia, also another category of Arabic is the other isolated dialects of Arabic, like the Judeo-Arabic, Mediterranean Arabic, Nubi Arabic, and the juba Arabic, which have greatly been affected by these communities' own pronunciation, culture and native tongue.
Dialect continuum
Arabic is a standard case of diglossia. The standard written language, Modern Standard Arabic, is based on the Classical Arabic of the Qur'an, while the modern vernacular dialects (or languages) branched from Classical Arabic a few hundred years earlier , from North Western Africa through Egypt, Sudan, and the Fertile Crescent to the Arabian Peninsula and Iraq. The dialects use different analogues from the huge Arabic language inventory, use different shortcuts and have been influenced by different substrate and superstrate languages. Adjacent dialects are mutually understandable to a large extent, but those from distant regions are not at all.
