Where has Eastern Armenian been used?

Eastern Armenian, historically referred to as the "Armenian of Russia," is a modern standard variety of the Armenian language. It was developed based on the dialects spoken in Yerevan, Armenia, and Tbilisi, Georgia.1

In the modern era, Eastern Armenian is prevalent in the following regions:

• Armenia: It serves as the primary language of the country.12
• Georgia: It is widely spoken by the Armenian population there.12
• Azerbaijan: It is used by Armenian speakers within the country.12
• Iran: It is spoken by the Armenian minority population.123

While Eastern and Western Armenian share much of their vocabulary, they possess significant differences in pronunciation and grammar, leading some to consider them distinct languages.1
