Iranian languages
branch of the Indo-Iranian languages in the Indo-European language family

The Iranian languages, or Iranic languages, are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples, mainly in the Iranian Plateau.
The Iranian languages are grouped in three stages: Old Iranian (until 400 BCE), Middle Iranian (400 BCE – 900 CE) and New Iranian (since 900 CE). The two directly attested Old Iranian languages are Old Persian (from the Achaemenid Empire) and Avestan (the language of the Avesta). Of the Middle Iranian languages, the better understood and recorded ones are Middle Persian (from the Sasanian Empire), Parthian (from the Parthian Empire), and Bactrian (from the Kushan and Hephthalite empires).
Number of speakers
In 2005, Ethnologue estimated that there are 86 languages in the group.
Terminology and grouping
Etymology
The term Iran derives directly from Middle Persian Ērān, first attested in a third-century inscription at Naqsh-e Rostam, with the accompanying Parthian inscription using the term Aryān, in reference to the Iranian peoples. The Middle-Iranian ērān and aryān are oblique plural forms of gentilic nouns ēr- (Middle Persian) and ary- (Parthian), both deriving from Proto-Iranian language *arya- (meaning "Aryan", i.e. "of the Iranians"). In the Iranic languages spoken on the plateau, the gentilic is attested as a self-identifier, included in ancient inscriptions and the literature of the Avesta, and remains also in other Iranian ethnic names Alan (Iron Ossetic: Ир Ir) and Iron (Ирон).
Iranian vs.
Begin with the source’s own compact description: “Iranian languages” is branch of the Indo-Iranian languages in the Indo-European language family. The dossier treats that line as a proposition to test through Iranian, languages and branch, not as a finished interpretation.
Why this record matters
The phrase “branch of the Indo-Iranian languages in the Indo-European language family” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q33527. The Library of Congress control number is sh85067921. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2005.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
