North Azerbaijani

North Azerbaijani, or Northern Azerbaijani, is the official language of the Republic of Azerbaijan. It is closely related to modern-day Istanbul Turkish, the official language of Turkey. It is also spoken in southern Dagestan, along the Caspian coast in the southern Caucasus Mountains and in scattered regions throughout Central Asia. As of 2011, there are some 9.23 million speakers of North Azerbaijani including 4 million monolingual speakers (many North Azerbaijani speakers also speak Russian, as is common throughout former USSR countries).

The Shirvan dialect as spoken in Baku is the basis of standard Azerbaijani. Since 1992, it has been officially written with a Latin script in the Republic of Azerbaijan, but the older Cyrillic script was still widely used in the late 1990s.

Ethnologue lists 21 North Azerbaijani dialects: "Quba, Derbend, Baku, Shamakhi, Salyan, Lenkaran, Qazakh, Airym, Borcala, Terekeme, Qyzylbash, Nukha, Zaqatala (Mugaly), Qabala, Nakhchivan, Ordubad, Ganja, Shusha (Karabakh), Karapapak, Kutkashen, Kuba".
