Khorasani Turkic is split into North, South and West dialects. The northern dialect is spoken in North Khorasan near Quchan; the southern in Soltanabad, near Sabzevar; the western, around Bojnord.
Khorasani Turkic was first classified as a separate dialect by Iranian Azerbaijani linguist Javad Heyat in the book Tārikh-e zabān o lahcayā-ye Türki (History of the Turkic dialects).[3] According to some linguists, it should be considered intermediate linguistically between Azerbaijani and Turkmen, although it is sufficiently distinct not to be considered a dialect of either.[3] It is considered by Turkic scholars to be most closely related to the other Oghuz varieties spoken in Iran, and a close relationship with Turkmen has been disputed on the basis of the comparisons of the core set of agglutinating morphemes.[4]
Doerfer and Hesche classify Khorasani Turkic into different branches within the Oghuz languages.[5]
Oghuz
Central Oghuz
Southeastern Khorasani Turkish
Southern Oghuz
Northwestern Khorasani Turkish
Southwestern Khorasani Turkish
Eastern Oghuz
Northern Khorasani Turkish
Northeastern Khorasani Turkish
According to Robert Lindsay, Khorasani Turkic has four branches:[6]
All vowels have phonemic length distinction. The vowel /ɑ/ is rounded to [ɒ] when followed by the vowels /u/, /i/ (sho& long /oː/ (Muxabbat[muxɒbbɑt] "love" , Insan[insɒn] "human"). On the other hand, short /o/ & all the remaining vowels do not cause this rounding, not even the mid & close vowels /e ø ɯ y/ & their long counterparts. (Yoldaşlık[joldɑʃlɯk] "friendship"). /ɑ/ is always pronounced [ɑ] in plurals (& for some speakers, it is pronounced as such unconditionally)

Nouns
Pluralization
Pluralization is marked on nouns with the suffix /-lar/, which has the two forms /-lar/ and /-lær/, depending on vowel harmony. As mentioned in the phonology section, plural /ɑ/ is never rounded to [ɒ], even when it follows /u/, /oː/ or /i/.
