Judeo-Tat or Juhuri (çuhuri / жугьури / ז'אוּהאוּראִ) is the traditional language of the Mountain Jews of the eastern Caucasus Mountains, especially Azerbaijan and Dagestan, now mainly spoken in Israel.
The language is a form of Persian; it belongs to the southwestern group of the Iranian division of the Indo-European languages. The Tat language, a similar, but still different language is spoken by the Muslim Tats of Azerbaijan, a group to which the Mountain Jews were mistakenly considered to belong during the era of Soviet historiography. The words Juvuri and Juvuro literally translate as "Jewish" and "Jews".
Judeo-Tat has Semitic ( Hebrew/ Aramaic/ Arabic) elements on all linguistic levels. Judeo-Tat has the Hebrew sound " ayin" (ע), whereas no neighbouring languages have it.
Judeo-Tat is an endangered language classified as "definitely endangered" by UNESCO's Atlas of the World's Languages in Danger.
