Armenian

The Armenian language (hayeren lezow, conventional short form hayeren) is an Indo-European language spoken by the Armenian people. It is the official language of the Republic of Armenia as well as Nagorno-Karabakh (a de facto republic but de-jure part of Azerbaijan). The language is also widely spoken by Armenian communities in the Armenian diaspora. Total speakers approximately 6.3 million.

Linguists typically classify Armenian as an independent branch of the Indo-European language family. Some Indo-Europeanists, notably Clackson (1994), have proposed that Armenian may have been grouped together with the Hellenic branch (Greek). This is called the Graeco-Armenian Hypothesis, in combination with a Graeco-Aryan hypothesis (Colin Renfrew, Clackson and Fortson 1994).
