Proto-Indo-Iranian, also calledProto-Indo-Iranic orProto-Aryan,[1] is thereconstructedproto-language of theIndo-Iranian branch ofIndo-European. Its speakers, the hypotheticalProto-Indo-Iranians, are assumed to have lived in the late 3rd millennium BC, and are often connected with theSintashta culture of theEurasian Steppe and the earlyAndronovo archaeological horizon.
Proto-Indo-Iranian was asatem language, likely removed less than a millennium from its ancestor, the lateProto-Indo-European language, and in turn removed less than a millennium from its descendants:Vedic Sanskrit (of theRigveda)[2] andOld Avestan (of theGathas).
It is the ancestor ofIndo-Aryan languages, theIranian languages, and theNuristani languages, predominantly spoken in theSouthern Asian subregion of Eurasia.

In addition to the vowels,*H, and*r̥ could function as the syllabic core. In many reconstructions, instances of*iH and*uH occur instead of*ī and*ū.
Proto-Indo-Iranian is hypothesized to have contained two series of stops or affricates in the palatal to postalveolar region.[3] The phonetic nature of this contrast is not clear, and hence they are usually referred to as the primary or first series (*ć *ȷ́ *ȷ́ʰ, continuing Proto-Indo-European palatovelar *ḱ *ǵ *ǵʰ) and the second or secondary series (*č *ǰ *ǰʰ, continuing Proto-Indo-European plain and labialized velars, *k, *g, *gʰ and *kʷ, *gʷ, *gʷʰ, in palatalizing contexts).The following table shows the most common reflexes of the two series (Proto-Iranian is the hypothetical ancestor to the Iranian languages, including Avestan and Old Persian):[4][5]

Proto-Indo-European is usually hypothesized to have had three to four laryngeal consonants, each of which could occur in either syllabic or non-syllabic positions. In Proto-Indo-Iranian, the laryngeals merged as one phoneme /*H/. Beekes suggests that some instances of this /*H/ survived into Rigvedic Sanskrit and Avestan as unwrittenglottal stops as evidenced by metrics.[6]
Like Proto-Indo-European and Vedic Sanskrit (and also Avestan, though it was not written down[7]), Proto-Indo-Iranian had apitch accent system similar to present-dayJapanese, conventionally indicated by an acute accent over the accented vowel.
The most distinctive phonological change separating Proto-Indo-Iranian from Proto-Indo-European is the collapse of theablauting vowels*e, *o into a single vowel, Proto-Indo-Iranian*a (but seeBrugmann's law).Grassmann's law,Bartholomae's law, and theruki sound law were also complete in Proto-Indo-Iranian.
A fuller list of some of the hypothesized sound changes from Proto-Indo-European to Proto-Indo-Iranian follows:

Proto-Indo-Iranian has preserved much of the morphology ofProto-Indo-European (PIE): thematic and athematic inflection in both nouns and verbs, all three numbers (singular, dual and plural), all the tense, mood and voice categories in the verb, and the cases in the noun.
Pronouns, nouns and adjectives are inflected into the eight cases of PIE: nominative, genitive, dative, accusative, vocative, ablative, locative and instrumental (with also a comitative/sociative meaning).
| Pronoun | PIE | PII |
|---|---|---|
| I | *éǵ > *eǵHóm | *aȷ́Hám > *aȷ́ʰám |
| You | *túh₂ | *túH |
| He | *ey- (*eyóm?) *só | *ayám *sá |
| She | *séh₂ | *sáH |
| It | *tód | *tád |
| We | *wéy > *weyóm | *wayám |
| You (all) | *yū́ | *yúH |
| They (m.) | *tóy | *táy |
| They (f.) | *téh₂es | *tā́s (or *táHas?) |
| They (n.) | *téh₂ | *táH |
In verbs, the chief innovation is the creation of a passive conjugation with the suffix*-yá, with middle inflection.[19]
The following examples lack the dual plural and are conjugated in the present tense.

Despite Proto-Indo-Iranian preserving much of the original morphology of Proto-Indo-European, an important innovation in the noun is the creation of a genitive plural ending*-nām used with vowel stems.[19]
