The Indo-Iranian 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 Indo-European languages are a language family native to the overwhelming majority of Europe, the Iranian plateau, and the northern Indian subcontinent. Some European languages of this family—English, French, Portuguese, Russian, Dutch, and Spanish—have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, of which there are eight groups with languages still alive today: Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic; another nine subdivisions are now extinct.
Avestan is an umbrella term for two Old Iranian languages, Old Avestan and Younger Avestan. They are known only from their conjoined use as the scriptural language of Zoroastrianism; the Avesta serves as their namesake. Both are early Eastern Iranian languages within the Indo-Iranian language branch of the Indo-European language family. Its immediate ancestor was the Proto-Iranian language, a sister language to the Proto-Indo-Aryan language, with both having developed from the earlier Proto-Indo-Iranian language; as such, Old Avestan is quite close in both grammar and lexicon to Vedic Sanskrit, the oldest preserved Indo-Aryan language.
Old Persian is one of two directly attested Old Iranian languages and is the ancestor of Middle Persian. Like other Old Iranian languages, it was known to its native speakers as ariya (Iranian). Old Persian is close to both Avestan and the language of the Rig Veda, the oldest form of the Sanskrit language. All three languages are highly inflected.
The ruki sound law, also known as the ruki rule or iurk rule, is a historical sound change that took place in the satem branches of the Indo-European language family, namely in Balto-Slavic, Armenian, and Indo-Iranian. According to this sound law, an original *s changed to *š after the consonants *r, *k, *g, *gʰ and the semi-vowels *w (*u̯) and *y (*i̯), as well as the syllabic allophones *r̥, *i, and *u:
The Scythian languages are a group of Eastern Iranic languages of the classical and late antique period, spoken in a vast region of Eurasia by the populations belonging to the Scythian cultures and their descendants. The dominant ethnic groups among the Scythian-speakers were nomadic pastoralists of Central Asia and the Pontic–Caspian steppe. Fragments of their speech known from inscriptions and words quoted in ancient authors as well as analysis of their names indicate that it was an Indo-European language, more specifically from the Iranic group of Indo-Iranic languages.
Median was the language of the Medes. It is an ancient Iranian language and classified as belonging to the Northwestern Iranian subfamily, which includes many other languages such as Kurdish, Old Azeri, Talysh, Gilaki, Mazandarani, Zaza–Gorani and Baluchi.
The Indo-Iranian peoples, also known as Ā́rya or Aryans from their self-designation, were a group of Indo-European speaking peoples who brought the Indo-Iranian languages to major parts of Eurasia in waves from the first part of the 2nd millennium BC onwards. They eventually branched out into the Iranian peoples and Indo-Aryan peoples.
The Iranian languages, also called the Iranic languages, are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples, predominantly in the Iranian Plateau.
Proto-Indo-Iranian, also called Proto-Indo-Iranic or Proto-Aryan, is the reconstructed proto-language of the Indo-Iranian branch of Indo-European. Its speakers, the hypothetical Proto-Indo-Iranians, are assumed to have lived in the late 3rd millennium BC, and are often connected with the Sintashta culture of the Eurasian Steppe and the early Andronovo archaeological horizon.
Brugmann's law, named for Karl Brugmann, is a sound law stating that in the Indo-Iranian languages, the earlier Proto-Indo-European *o normally became *a in Proto-Indo-Iranian but *ā in open syllables if it was followed by one consonant and another vowel. For example, the Proto-Indo-European noun for 'wood' was *dόru, which in Vedic became dāru. Everywhere else, the outcome was *a, the same as the reflexes of PIE *e and *a.
Saka, or Sakan, was a variety of Eastern Iranian languages, attested from the ancient Buddhist kingdoms of Khotan, Kashgar and Tumshuq in the Tarim Basin, in what is now southern Xinjiang, China. It is a Middle Iranian language. The two kingdoms differed in dialect, their speech known as Khotanese and Tumshuqese.
The Eastern Iranian languages are a subgroup of the Iranian languages, having emerged during the Middle Iranian era. The Avestan language is often classified as early Eastern Iranian. As opposed to the Middle-era Western Iranian dialects, the Middle-era Eastern Iranian dialects preserve word-final syllables.
The Western Iranian languages or Western Iranic languages are a branch of the Iranian languages, attested from the time of Old Persian and Median.
Khvarenah (also spelled khwarenah or xwarra(h): Avestan: 𐬓𐬀𐬭𐬆𐬥𐬀𐬵xᵛarənah) is an Avestan word for a Zoroastrian concept literally denoting "glory" or "splendour" but understood as a divine mystical force or power projected upon and aiding the appointed. The neuter noun thus also connotes "(divine) royal glory", reflecting the perceived divine empowerment of kings. The term also carries a secondary meaning of "(good) fortune"; those who possess it are able to complete their mission or function.
The Iranian peoples or Iranic peoples are a diverse grouping of peoples who are identified by their usage of the Iranian languages and other cultural similarities.
Iranian literature, or Iranic literature, refers to the literary traditions of the Iranian languages, developed predominantly in Iran and other regions in the Middle East and the Caucasus, eastern Asia Minor, and parts of western Central Asia and northwestern South Asia. These include works attested from as early as the 6th century BC. Modern Iranian literatures include Persian literature, Ossetian literature, Kurdish literature, Pashto literature, and Balochi literature, among others.

Arya was the ethnonym used by Iranians during the early History of Iran. In contrast to cognates of Arya used by the Vedic people and Iranic steppe nomads, the term is commonly translated using the modern ethnonym Iranian.
