Neo-Aramaic dialect of Bohtan

Bohtan Neo-Aramaic is a dialect of Northeastern Neo-Aramaic originally spoken by ethnic Assyrians on the plain of Bohtan in the Ottoman Empire. Its speakers were displaced during the Assyrian genocide in 1915 and settled in Gardabani, near Rustavi in Georgia, Göygöl and Ağstafa in Azerbaijan. However it is now spoken in Moscow, Krymsk and Novopavlosk, Russia. It is considered to be a dialect of Assyrian Neo-Aramaic since it is a northeastern Aramaic language and its speakers are ethnically Assyrians.
The closest related dialect is Hertevin, and Bohtan also shares many similarities with the peripheral Qaraqosh dialect.
History.
Before World War I, there were around 30,000 speakers of Bohtan Neo-Aramaic on the Plain of Bohtan, around the town of Cizre in Turkey's Sirnak Province. Mostly members of the Assyrian Church of the East, their language was a northern dialect of the more common Assyrian languages, Assyrian Neo-Aramaic and Chaldean Neo-Aramaic, but already somewhat more conservative than the standard Alqosh dialect. With the Assyrian Genocide that hit the Assyrians in eastern Turkey at the end of the war, many were forced from their homes.
A decimated population travelled from Bohtan and eventually resettled in Gardabani in southeastern Georgia, 530 km from their original home. Many of the speakers of Bohtan Neo-Aramaic are over sixty year of age. The younger generations tend to use Georgian or Russian instead. According to recent studies, these communities have moved to Southern Russia, in the towns of Krymsk and Novopavlosk.
Genealogy.
This dialect is derived from the Northeastern Neo-Aramaic (NENA) languages, which is made up by Bohtan Neo-Aramaic, Assyrian Neo-Aramaic, Chaldean Neo-Aramaic, Hertevin, Senaya and Koy Sanjat Surat. Bohtan refers to the area between the Tigris and Bohtan river . The dialect mostly spoken by Christian communities.
The Neo-Aramaic language is classified under Afroasiatic and the Bohtan dialect is more specifically one of the NENA dialects which are found south-eastern Turkey, northern Iraq and western Iran Due to the dislocation of NENA speakers, neighboring languages have influenced the dialects, such as Kurdish.
One of the latest studies of the language was carried out by Samuel Ethan Fox in 1999, showing that Bohtan Neo-Aramaic has retained many conservative features of Chaldean and Assyrian Neo-Aramaic which are not present in the standard Alqosh and Urmia dialects, but has also developed new features that are not present in other dialects.
Phonology.
Bohtan's consonant inventory is typical of other NENA dialects. Unlike Hertevin, it merges /ħ/ and /x/ into /x/.
Status.
Bohtan Neo-Aramaic is considered as a severely endangered language as it is estimated to have less than 500 speakers, mostly found in the former Soviet Union. Due to migration and intermarriage, younger generations speak the language less fluently and are expected to know Russian or Turkish as their first language.
