Indo-Iranian languages



The Indo-Iranian languages (also known as Indo-Iranic languages or collectively the Aryan languages ) constitute the largest and southeasternmost extant branch of the Indo-European language family. They include over 300 languages, spoken by around 1.5 billion speakers, predominantly in South Asia, West Asia and parts of Central Asia.

The areas with Indo-Iranian languages stretch from Europe (Romani) and the Caucasus (Ossetian, Tat and Talysh), down to Mesopotamia and eastern Anatolia (Kurdish languages, Gorani, Kurmanji Dialect continuum, Zaza ), the Levant (Domari) and Iran (Persian), eastward to Xinjiang (Sarikoli) and Assam (Assamese), and south to Sri Lanka (Sinhala) and the Maldives (Maldivian), with branches stretching as far out as Oceania and the Caribbean for Fiji Hindi and Caribbean Hindustani respectively. Furthermore, there are large diaspora communities of Indo-Iranian speakers in northwestern Europe (the United Kingdom), North America (United States, Canada), Australia, South Africa, and the Persian Gulf Region (United Arab Emirates, Saudi Arabia). The number of distinct languages listed in Ethnologue are 312, while those recognised in Glottolog are 320. The Indo-Iranian language with the largest number of native speakers is Hindustani language (Hindi-Urdu).

Etymology
The term Indo-Iranian languages refers to the spectrum of Indo-European languages spoken in the Southern Asian region of Eurasia, spanning from the Indian subcontinent (where the Indic branch is spoken, also called Indo-Aryan) up to the Iranian Plateau (where the Iranic branch is spoken).

This branch is also known as Aryan languages, referring to the languages spoken by Aryan peoples, where the term Aryan is the ethnocultural self-designation of ancient Indo-Iranians. But in modern-day, Western scholars avoid the term Aryan since World War II, owing to the perceived negative connotation associated with Aryanism.

Origin
Historically, the Indo-Iranian speakers, both Iranians and Indo-Aryans, originally referred to themselves as the Aryans. The Proto-Indo-Iranian-speakers generally associated with the Sintashta culture,  which is thought to represent an eastward migration of peoples from the Corded Ware culture. The earliest known chariots have been found in Sintashta burials, and the culture is considered a strong candidate for the origin of the technology, which spread throughout the Old World and played an important role in ancient warfare. There is almost a general consensus among scholars that the Andronovo culture, the successor of Sintasha culture, was an Indo-Iranian culture. Currently, only two sub-cultures are considered as part of Andronovo culture: Alakul and Fëdorovo cultures. The Andronovo culture is considered as an "Indo-Iranic dialect continuum", with a later split between Iranian and Indo-Aryan languages. However, according to Hiebert, an expansion of the Bactria–Margiana Archaeological Complex (BMAC) into Iran and the margin of the Indus Valley is "the best candidate for an archaeological correlate of the introduction of Indo-Iranian speakers to Iran and South Asia", despite the absence of the characteristic timber graves of the steppe in the Near East, or south of the region between Kopet Dag and Pamir-Karakorum. J. P. Mallory acknowledges the difficulties of making a case for expansions from Andronovo to northern India, and that attempts to link the Indo-Aryans to such sites as the Beshkent and Vakhsh cultures "only gets the Indo-Iranian to Central Asia, but not as far as the seats of the Medes, Persians or Indo-Aryans". He has developed the Kulturkugel (lit. 'the culture bullet') model that has the Indo-Iranians taking over cultural traits of BMAC, but preserving their language and religion while moving into Iran and India.
