:''This article deals with the language family. For languages spoken on the territory of
Iran, see
Languages of Iran.''
The 'Iranian languages' are a branch of the
Indo-European language family. With the
Indo-Aryan languages they form the
Indo-Iranian languages group.
Avestan and
Old Persian are the oldest recorded Iranian languages.
Today, there are an estimated 150-200 million native speakers of Iranian languages.
[1] The 2005
SIL enumerates 87 varieties of Iranian languages, per number of native speakers, the greatest are
Persian (ca. 70 million),
Kurdish and
Pashto (ca. 25 million each), and
Balochi (ca. 7 million); to compare these numbers against those for other languages, see
list of languages by number of native speakers.
Name
The 'Iranian' languages branch is so named because its principal member languages, including
Persian, have been spoken in the area of the
Iranian plateau since ancient times, however, as a linguistic classification, 'Iranian' implies no relation with the country of
Iran, for which see
Languages of Iran.
Early Iranian languages
The Indo-Iranian languages probably originated in
Central Asia. The
Andronovo culture is the suggested candidate for the common Indo-Iranian culture ''ca''.
2000 BC.
Together with the other Indo-Iranian languages, the Iranian languages are descended from a common ancestor,
Proto-Indo-Iranian. This language split up into:
★
Indo-Aryan languages, including
Sanskrit, attested from the
2nd millennium BC
★
Dardic languages
★
Nuristani languages
★ Iranian languages, including
Avestan (dated to roughly
1000 BC) and
Old Persian (attested from roughly
500 BC).
'Proto-Iranian' thus dates to some time after Proto-Indo-Iranian breakup, or the early second millennium BC, as the Old Iranian languages 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.
Linguistically, the Old Iranian languages are divided into two major families and sub classes:
★ The eastern group
★ The western group
★
★ The southwestern group
★
★ The northwestern group
The eastern group includes the
Sogdian,
Khwarezmian,
Saka, and
Avestan, (also known as ''Old Bactrian''). The northwestern branch includes the
Median and
Kurdish. The southwestern group includes
Persian.
Avestan is mainly attested through the
Avesta, a collection of sacred texts connected to the
Zoroastrian religion. Old Persian is attested through inscriptions in the
Old Persian cuneiform script.
The Middle Iranian languages
What is known in Iranian linguistic history as the "Middle Iranian" era is thought to begin around the
4th century BCE lasting through the
9th century. Again, geographically, one can classify these into two main families,
Western and
Eastern.
The former family includes the languages of
Parthian (
Arsacid Pahlavi) and
Middle Persian, while
Bactrian,
Sogdian,
Khwarezmian,
Saka, and
Old Ossetic (Scytho-Sarmatian) fall under the latter category. The two languages of the western group were linguistically very close to each other, but quite distinct from their eastern counterparts. On the other hand, the Eastern group retained more proximity to Old Iranian. They were inscribed in various Aramaic alphabets, which had evolved from the
Achaemenid Imperial Aramaic.
Middle Persian (Pahlavi), was the official language of the
Sassanids. It was in usage from the 3rd century until the top of the 10th century. Pahlavi was also the language of the
Manichaeans, whose texts survive albeit in limited numbers. The ''Imperial Aramaic'' script used in this era experienced significant maturation.
Iranian languages after the Arab conquest of Persia

Following the
Islamic Conquest of Iran, there were important changes in the role of the different dialects of Persian within the Persian empire. The old prestige form of
Middle Persian, also known as
Pahlavi, was replaced by a new standard dialect called
Dari as the official language of the court. The name Dari comes from the word ''darbar'' (دربار), which refers to the royal court, where many of the poets, protagonists, and patrons of the literature flourished (''See
Persian literature''). The
Saffarid dynasty in particular was the first in a line of many dynasties to officially adopt the new language in 875CE. Dari is believed to have been heavily influenced by regional dialects of eastern Iran, whereas the earlier
Pahlavi standard was based more on western dialects. This new prestige dialect became the ancestor of modern Standard Persian. Medieval Iranian scholars such as
Abdullah Ibn al-Muqaffa (8th century) and
Ibn al-Nadim (10th century) associated the term "Dari" with the eastern province of
Khorasan, while they used the term "Pahlavi" to describe the dialects of the northwestern areas between
Isfahan and
Azerbaijan (see
Ancient Azari language), and "Parsi" ("Persian" proper) to describe the dialects of
Fars. They also noted that the unofficial language of the royalty itself was yet another dialect, "Khuzi", associated with the western province of
Khuzestan.
The Islamic conquest also brought with it the adoption of Arabic script for writing Persian. It was adapted to the writing of Persian by the addition of a few letters. This development probably occurred some time during the second half of the 8th century, when the old middle Persian script began dwindling in usage. The aforementioned script remains the in use in contemporary modern Persian. Tajik script was first
Latinised in the
1920s under the then Soviet nationality policy. The script was however subsequently
Cyrillicized in the 1930s under plans by
USSR's government in
Central Asia.
The geographical area in which Iranian languages were spoken was pushed back in several areas by new neighbouring languages. Arabic spread into some parts of Western Iran (
Khuzestan), and
Turkic languages spread through much of Central Asia, displacing various Iranian languages such as
Sogdian and
Bactrian in parts of what is today
Turkmenistan,
Uzbekistan and
Tajikistan. They also displaced the Persian language spoken in
Azerbaijan.
Classification of the Iranian languages
Main articles: List of Iranian languages
Iranian languages are divided into
Eastern and
Western subfamilies, totalling about 84 languages (SIL estimate). Of the most widely-spoken Iranian languages,
Kurdish,
Persian, and
Balochi are all Western Iranian languages, while
Pashto is an Eastern Iranian language.
