TheEastern Iranian languages orEastern Iranic languages[1] are an areal[b] subgroup of theIranian languages, having emerged during theMiddle Iranian era (4th century BC to 9th century AD). TheAvestan language is often classified as early Eastern Iranian. As opposed to the Middle-eraWestern Iranian dialects, the Middle-era Eastern Iranian dialects preserve word-final syllables.
The largest living Eastern Iranian language isPashto, with 40 to 60 million speakers[2] between theOxus River in Afghanistan and theIndus River in Pakistan. The second-largest living Eastern Iranian language isOssetic, with roughly 600,000 speakers acrossOssetia (split betweenGeorgia and Russia). All other languages of the Eastern Iranian subgroup have fewer than 200,000 speakers combined.
Most living Eastern Iranian languages are spoken in a contiguous area: southern and eastern Afghanistan and the adjacent parts of western Pakistan; theBadakhshan Mountainous Autonomous Region in easternTajikistan; and the westernmost parts ofXinjiang Uyghur Autonomous Region in western China. There are also two living members in widely separated areas: theYaghnobi language of northwestern Tajikistan (descended fromSogdian); and the Ossetic language of theCaucasus (descended fromScytho-Sarmatian and is hence classified as Eastern Iranian despite its location). These are remnants of a vast ethno-linguistic continuum that stretched over most ofCentral Asia, parts of the Caucasus, Eastern Europe, andWestern Asia in the 1st millennium BC — an area otherwise known asScythia. The large Eastern Iranian continuum in Eastern Europe would continue up to the 4th century AD, with the successors of the Scythians, namely theSarmatians.[3]
Western Iranian is thought to have separated fromProto-Iranian in the course of the later 2nd millennium BC not long afterAvestan, possibly occurring in theYaz culture. Eastern Iranian followed suit, and developed in place of Proto-Iranian, spoken within theAndronovo horizon.
Due to theGreek presence in Central Asia, some of the easternmost of these languages were recorded in theirMiddle Iranian stage (hence the "Eastern" classification), while almost no records of the Scytho-Sarmatian continuum stretching from Kazakhstan west across thePontic steppe to Ukraine have survived. Some authors find that the Eastern Iranian people had an influence on Russian folk culture.[4]

Middle Persian/Dari spread around the Oxus River region, Afghanistan, andKhorasan after the Arab conquests and during Islamic-Arab rule.[5][6] The replacement of the Pahlavi script with the Arabic script in order to write the Persian language was done by the Tahirids in 9th century Khorasan.[7] The Persian Dari language spread, leading to the extinction of Eastern Iranic languages includingBactrian andKhorezmian. Only a few speakers of theSogdian descendedYaghnobi remain among the largely Persian-speaking Tajik population of Central Asia. This appears to be due to the large numbers of Persian-speakers in Arab-Islamic armies that invaded Central Asia and later Muslim governments in the region such as theSamanids.[8] Persian was rooted into Central Asia by the Samanids.[9]
Eastern Iranian remains in large part a dialect continuum subject to common innovation. Traditional branches, such as "Northeastern", as well as Eastern Iranian itself, are better consideredlanguage areas rather than genetic groups.[10][11]
The languages are as follows:[12]
Avestan is sometimes classified as Eastern Iranian, but is not assigned to a branch in 21st-century classifications.
The Eastern Iranian area has been affected by widespreadsound changes, e.g. t͡ʃ > ts.
| English | Avestan | Pashto | Munji | Sanglechi | Wakhi | Shughni | Parachi | Ormuri | Yaghnobi | Ossetic |

Common to most Eastern Iranian languages is a particularly widespreadlenition of the voiced stops *b, *d, *g. Between vowels, these have been lenited also in most Western Iranian languages, but in Eastern Iranian,spirantization also generally occurs in the word-initial position. This phenomenon is however not apparent in Avestan, and remains absent from Ormuri-Parachi.
A series ofspirant consonants can be assumed to have been the first stage: *b > *β, *d > *ð, *g > *ɣ. Thevoiced velar fricative/ɣ/ has mostly been preserved. The labial member has been well-preserved too, but in most languages has shifted from avoiced bilabial fricative/β/ to thevoiced labiodental fricative/v/. The dental member has proved the most unstable: while avoiced dental fricative/ð/ is preserved in some Pamir languages, it has in e.g. Pashto and Munji lenited further to/l/. On the other hand, in Yaghnobi and Ossetian, the development appears to have been reversed, leading to the reappearance of a voiced stop/d/. (Both languages have also shifted earlier *θ >/t/.)
| English | Avestan | Pashto | Munji | Sanglechi | Wakhi | Shughni | Parachi | Ormuri | Yaghnobi | Ossetic |
|---|---|---|---|---|---|---|---|---|---|---|
| ten | dasa | las | los / dā1 | dos | δas | δis | dōs | das | das | dæs |
| cow | gav- | ɣwā | ɣṓw | uɣūi | ɣīw | žōw | gū | gioe | ɣōw | qug |
| brother | brātar- | wrōr | vəróy | vrūδ | vīrīt | virṓd | byā | (marzā2) | virṓt | ærvad3 |
The consonant clusters *ft and *xt have also been widely lenited, though again excluding Ormuri-Parachi, and possibly Yaghnobi.
The neighboringIndo-Aryan languages have exerted a pervasive external influence on the closest neighbouring Eastern Iranian, as it is evident in the development in theretroflex consonants (in Pashto, Wakhi, Sanglechi, Khotanese, etc.) and aspirates (in Khotanese, Parachi and Ormuri).[10] A more localized sound change is the backing of the former retroflex fricativeṣ̌[ʂ], tox̌[x] or tox[χ], found in the Shughni–Yazgulyam branch and certain dialects of Pashto. E.g. "meat":ɡuṣ̌t in Wakhi andγwaṣ̌a in Southern Pashto, but changes toguxt in Shughni,γwax̌a in Central and Northern Pashto.
Estimates of the number of Pashto speakers range from 40 million to 60 million...
