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.
Dual (grammatical number)
Among living languages, Modern Standard Arabic has a mandatory dual number, marked on nouns, verbs, adjectives and pronouns. (First-person dual forms, however, do not exist; compare this to the lack of third-person dual forms in the old Germanic languages.) Many of the spoken Arabic dialects have a dual marking for nouns (only), and its use can be mandatory in some dialects, and not mandatory in others. Likewise, Akkadian had a dual number, though its use was confined to standard phrases like "two hands", "two eyes", and "two arms". The dual in Hebrew has also atrophied, generally being used for only time, number, and natural pairs even in its most ancient form.
