Talysh language in the context of "Talysh Khanate"

Talysh Mountains (Azerbaijani: Talış dağları, Persian: کوه‌های تالش, romanized: kuh-hâye tâleš, Talysh: Tolışə bandon) is a mountain range in far southeastern Azerbaijan and far northwestern Iran within Ardabil Province and Gilan Province.

Proto-Iranian or Proto-Iranic is the reconstructed proto-language of the Iranian languages branch of Indo-European language family and thus the ancestor of the Iranian languages such as Persian, Pashto, Sogdian, Zazaki, Ossetian, Mazandarani, Kurdish, Talysh and others. Its speakers, the hypothetical Proto-Iranians, are assumed to have lived in the 2nd millennium BC and are usually connected with the Andronovo archaeological horizon (see Indo-Iranians).

Proto-Iranian was a satem language descended from the Proto-Indo-Iranian language, which in turn, came from the Proto-Indo-European language. It was likely removed less than a millennium from the Avestan language, and less than two millennia from Proto-Indo-European.

Tālīsh (Talysh: Tolış; Azerbaijani: Talış; Persian: تالش, romanized: Tālesh) is a region in the southwestern coast of the Caspian Sea. It is a homeland of the indigenous Talysh people, who inhabit the region and speak the Talysh language. The territory and the language set apart Talish from its neighbors.

Talish is now divided between Azerbaijan and Iran. It stretches north from the Sefīd-Rūd river, which cuts through the Alborz mountains in Iran's Gilan province, to the Aras river in the south of the Republic of Azerbaijan.

Median (also Medean or Medic) is an extinct Iranian language which was spoken by the now extinct ancient Medes. It belongs to the Northwestern branch of the Iranian language family, which includes many other much more recently attested and different languages such as Kurdish, Old Azeri, Talysh, Gilaki, Mazandarani, Zaza, Gorani and Baluchi.

The Talysh people (Talysh: Tolışon, تالشان) or Talyshis, Talyshes, Talyshs, Talishis, Talishes, Talishs, Talesh are an Iranian ethnic group, with the majority residing in Azerbaijan and a minority in Iran. They are the indigenous people of the Talish, a region on the western shore of the Caspian Sea shared between Azerbaijan and Iran. The main city of the Talysh people and their homeland is Lankaran, the majority of the population of which is ethnically Talysh. They speak the Talysh language, one of the Northwestern Iranian languages. The majority of Talyshis in Azerbaijan are Shiite Muslims, and predominantly Sunni in Iran.

The Talysh people are famous for their longevity and centenarianism.

Old Azeri (آذری, Āzarī; also spelled Adhari, Azeri or Azari) is the extinct Iranian language that was once spoken in the northwestern Iranian historic region of Azerbaijan (Iranian Azerbaijan) before the Turkification of the Azerbaijani people. Some linguists believe the southern Tati varieties of Iranian Azerbaijan around Takestan such as the Harzandi and Karingani dialects to be remnants of Old Azeri. Along with Tat dialects, Old Azeri is known to have strong affinities with Talysh and Zaza language and Zaza and Talysh are considered to be remnants of Old Azeri. Iranologist linguist W. B. Henning demonstrated that Harzandi has many common linguistic features with both Talysh and Zaza and positioned Harzandi between the Talysh and Zaza.

Old Azeri was the dominant Iranic language in Azerbaijan before it was replaced by Azerbaijani, which is a Turkic language.

The Tati language (Tati: تاتی زبون, Tâti Zobun) is a Northwestern Iranian language spoken by the Tat people of Iran which is closely related to other languages such as Talysh, Zaza, Mazandarani and Gilaki.
