The Iranian languages are a part of the Indo European language family. The Iranian language group is part of the larger Indo-Iranian language subfamily and accounts for some of the oldest-recorded Indo-European languages. Indo-Iranian languages originated around modern Afghanistan, and split into the Iranian, Indo-Aryan, Dardic, and Nuristani language groups as the speakers of Proto-Indo-Iranian moved west, east, and south.
Some Iranian authors use the term "Iranianlanguages" in a looser, non-linguistic sense, including all languages spoken by people who regard themselves as part of the Iranian nation, or by ancient peoples whose cultures Iranians today regard as part of their national heritage.
The Old Iranianlanguages began to break off and evolve separately as the various Iranian tribes migrated and settled in vast areas of southeastern Europe, the Iranian plateau, and Central Asia.
Language is a system of conventional spoken or written symbols by means of which human beings, as members of a social group and participants in its culture, communicate.
Languages of the Finno-Ugric family, such as languages of the Sami (Lapp) and Baltic-Finno groups (e.g., Sami, Finnish, and Livonian), are spoken in parts of Norway, Sweden, Finland, and Russia.
The languages of North Asia are those spoken from the Arctic Ocean on the north to South Asia and China on the south and from the Caspian Sea and Ural Mountains in the west to the Pacific Ocean in the east.
