Descriptive phonology

Two palatal series

Proto-Indo-Iranian is hypothesized to have contained two series of stops or affricates in the palatal to postalveolar region. 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):

Laryngeal

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 unwritten

Accent

system similar to present-day Japanese, conventionally indicated by an acute accent over the accented vowel.

Historical phonology

The most distinctive phonological change separating Proto-Indo-Iranian from Proto-Indo-European is the collapse of the ablauting vowels ''*e, *o'' into a single vowel, Proto-Indo-Iranian ''*a'' (but see Brugmann's 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: * The Satem shift, consisting of two sets of related changes. The PIE palatals *ḱ *ǵ *ǵʰ are fronted or affricated, eventually resulting in PII *ć, *ȷ́, *ȷ́ʰ, while the PIE labiovelars *kʷ *gʷ *gʷʰ merge with the velars *k *g *gʰ. * The PIE liquids merge as .Fortson, p. 182 * The PIE syllabic nasals merge with . *

: an aspirate immediately followed by a voiceless consonant becomes voiced stop + voiced aspirate. In addition, dʰ + t > dᶻdʰ.Fortson, p. 181 * The Ruki rule: *s is retracted to *š when immediately following a liquid (*r *r̥ *l *l̥), a high vowel (*i *u), a PIE velar (*ḱ *ǵ *ǵʰ *k *g *gʰ *kʷ *gʷ *gʷʰ) or the syllabic laryngeal *H̥. Its allophone *z likewise becomes *ž. * Before a dental occlusive, *ć becomes *š and *ȷ́ becomes *ž. *ȷ́ʰ also becomes *ž, with aspiration of the occlusive. * The sequence *ćš was simplified to *šš. * The "second palatalization" or "law of palatals": *k *g *gʰ develop palatal allophones *č *ǰ *ǰʰ before the front vowels *i, *e. through an intermediate *kʲ *gʲ *gʲʰ. * Brugmann's law: *o or *ó in an open syllable lengthens to *ā.Fortson, p. 183 * The vowels *e *o merge with *a. Similarly, *ē, *ō merge with *ā. This has the effect of giving full phonemic status to the second palatal series *č *ǰ *ǰʰ. * In certain positions, laryngeals were vocalized to *i. This preceded the second palatalization. :* Following a consonant, and preceding a consonant cluster :* Following a consonant and word-final * The Indo-European laryngeals all merged into one phoneme *H, which may have been a glottal stop. This was probably contemporary with the merging of *e and *o with *a. * According to Lubotsky's Law, *H disappeared when followed by a voiced nonaspirated stop and another consonant:Beekes

Subsequent sound changes

(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.

Personal pronouns (nominative case)

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).

Three examples of verbs

In verbs, the chief innovation is the creation of a passive conjugation with the suffix ''*-yá'', with middle inflection.Fortson p. 205 The following examples lack the dual plural and are conjugated in the present tense.

Examples of noun declension

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. The following examples lack the dual number.

Masculine noun

Feminine noun

Neuter noun

An example of adjectival declension

The morphology in adjectival declension is identical to the one in noun declension. The following example lacks the dual number.
