Map of areas where Aryan is believed to have once been spoken

Aryan (*Airás, pronounced /əi̯ˈrəs/), also referred to as Pre-Proto-Indo-European, is an ab interiori language depicting the transition from Paleolithic Codes to Proto-Indo-European (PIE). There are no historical records of its existence, or comparative data to support it; rather, it is an abductive experiment based on the hypothesis of Transitional Dialects.

In most of known History, indo-european speaking populations have been widespread in Eurasia, bearing fruits from civilizations such as those of the Roman Empire, the Hellenistic City-States, and the Rigvedic Tribes. Memorable personalities who spoke natively dialects from those areas include the roman general Julius Caesar (speaker of Latin), the macedonian king Alexander the Great (speaker of Ancient Greek), the nazi chancellor Adolf Hitler (speaker of German), the french emperor Napoleon Bonaparte (speaker of Corsican), the british physicist Isaac Newton (speaker of English), the italian renascentist Leoanardo da Vinci (speaker of Tuscan Italian), the indian ascetic Gautama Buddha (speaker of Prakrit), et cetera. As of the 21^st Century, half of the world's population speaks 454 indo-european languages, with the Americas, Europe, Iran, Pakistan, and India being today the centers of native speakers due the Indo-European Migrations and European Colonialism.

The origin of the ancestor of indo-european languages is ...

In the hybrid model, Aryan must have been spoken somewhere near the Caucasus Mountains in compliance with the Armenian Hypothesis, which in its current form holds that the speakers of "Pre-Proto-Indo-European" pertained to the genepool of the Caucasian Hunter-Gatherers (CHG), who would eventually contribute to the formation of the Yamnaya Culture and the dispersion of "Core Proto-Indo-European" as detailed in the Kurgan Hypothesis. The age of the language is more controversial, being set between 12,000 and 10,000 years Before Present (BP), or the double of its daughter-language's, to coincide with the notion of Linguistic Modernity.

History

Development from Paleolithic Codes

The history of Aryan taken into account starts with the transition from Atomism to Double Articulation by the dialects of the Upper Paleolithic, mostly regarding the Pangaean Code as its ultimate source, next to the influence of the Diluvian and Hyperborean Codes. Although the actor responsible for this transition is a matter of debate even within the experiment, the loss of archaic features is assumed to coincide with the End of the Last Ice Age. At that time (12,000 BP), the loss of strict adherence to the primordial grammar might have allowed sound changes to take place, as seen below.

• Weak (plosive) stops become aspirated/murmured preceding a laryngeal consonant, as strong (ejective/implosive) stops gain plosive qualities in the same position.

/tH/→/th/	/tʼH/→/t/	/dH/→/dɦ/	/ɗH/→/d/

• The production of aspirated/murmured series contaminates the regular sounds, whose qualities of WEAK and STRONG are rearranged to accomodate Aspiration/Breathy Voice instead of Ejection/Implosion.

• Sonorants, contrary to the stop series, remain conserved when onset; however, they collapse as voiced codas.

In Morphology, Aryan introduced a series of innovations by mixing and developing peculiarities from different Paleolithic Codes. The Hyperborean nominative -s for example was probably borrowed via another caucasian substrate, which completely assumed the role of epenthetic root (next to Aryan *-ar) in the construction "ROOT₁ ROOT₂". Primordial [ˈn̠ʕih ˈə] "old" would therefore yield *knīás "old" (=*knih₁ *ás) [PIE *sénos "old"]. Furthermore, this development culminated into the Indo-European Ablaut. That is: when the accent falls into the epenthetic root, the first root suffers a phonetic change influenced by the interaction between laryngeals and vowels, which fuse into diphthongs or long vowels. This effect is considered a reflex of Umlaut in the Pangaean Code, where guttural fricatives can alternate between their vocalic equivalents and even modify the qualities of the nucleus.

Correspondences:

• gʰedʰ "to join" < *gʰdʰ- "to gather" < g̟
• gʰabʰ ~ gʰeh₁bʰ- "to seize" < *pʰkʰ- "to take" < p̟

In a root with a cluster, if there is no consonant as coda except:

-a laryngeal, the laryngeal is erased and the second element of the cluster becomes the coda.

*gʰedʰ- (PIE) < ((*gʰed-)) < *gʰdʰih₁- (Aryan) < g̟ʕih (Codex)

-a liquid, the liquid is incorporated and the first element of the cluster becomes the coda.

*(s)pregʰ- ~ *sper- (PIE) < ((*bregʰ-)) < *gbair- (Aryan) < ɠ̠ʕihr (Codex)

exception: roots with longs vowels [dʰuh2- < pʰtʰūh1- (**pʰūt)]

h1egóM < aikṓm < aku ˈᴇːʔ > *ēh0 (Aryan) > *ih2 (PIE) uˈħihurk̟ʼ-a > *h₂úrkʰtʰa > *h₂ŕ̥tḱoes

• i and *u disappear before sonorants

mur, mrás > mer as PIE only accepts thorn clusters...

The language is demonstrared using two modern Indo-European languages (German and Russian) and two ancient ones (Latin and Greek).

mobile roots: -*r "quality" -*m "result" -*dʰ "fixation"

NOTE: PIE neuter particle *-om derives from Aryan *(_)-am, which forms result nouns

Notes for table 1:

Consonant clusters

Proto-Indo-European also had numerous consonant clusters, such as *st, *ḱs. In most cases in most languages, each consonant in a cluster develops according to the normal development given in the table above. Many consonant clusters however also show special developments in multiple languages. Some of these are given by the following table (with cases of otherwise predictable development in gray):

Historical and Geographical Distribution

Since Lazaridis et al's paper, absence of Eastern European Hunter-Gatherer (EHG) ancestry in the Anatolian component of the Indo-European speaking populations has suggested a caucasian homeleand for earlier stages of PIE rather than a pre-Yamnaya pontic continuance. Recent studies, furthermore, point to a total farming economy by the Zagros around 6,000 BC, which tempts an older dating for a Transitional Dialect such as Aryan.

Phonology

Consonants

Aryan is reconstructed as having 36 consonants, with an assumption made that it would have maintained the basic inventory of the Pangaean Code in some form. In comparison, PIE is often reconstructed as having 24 consonants.

Vowels

While the simplicity of the vocalic inventory of PIE (constituted exclusively of *e, *o, *ē, and *ō, ignoring allophones of syllabic consonants and diphthongs with sonorants) has inspired some researchers to draw connections with language families of similar conditions near the Pontic–Caspian Steppe, such as the Pontic Hypothesis witht the Northwest Caucasian Languages, Aryan is reconstructed instead with a rich system of monophthongs, diphthongs, and even triphthongs.

Morphology

Affix

• gʷaináh0
• gʷaināsyas
• gʷaināsay, *gʷaināmas

Aryan has only zero-grade (∅) and full grade (_)

*(_)-as [forms active animate nouns] EX: kʰúh2as "sound" = PIE *(é)-os in *ḱlewos
*(∅)-ás [forms active animate adjectives] EX: *pdás "capable to step" = PIE *(e)-ós in *pṓds
*(á)-as [forms passive animate nouns] EX: ... = PIE *(ó)-os in ...
*(a)-ás [forms passive animate adjectives] EX: = PIE *(o)-ós, *the construction became agentive instead of passive in PIE, but some archaic forms remain, such as *gʰoysós "spear"
*(_)-ar [forms active inanimate nouns] EX: *húdar "water" = PIE *-r̥ in *wódr̥
*(∅)-ár [forms active inanimate adjectives] 
*(á)-ar [forms passive inanimate nouns]
*(a)-ár [forms passive inanimate adjectives]

mas

*(_)-tár [forms agent nouns]
*(_)-tram [forms instrument nouns] *fusion of *(_)-tár [agent particle] and *-am [neuter particle]
*(∅)-C-ás [forms derived nouns through mobile roots] EX: *pʰtʰūymás PIE = PIE *(∅)-mós

Root

In Aryan, roots are either static or mobile. In the first case, they serve as a prototypical source of meaning, impossible to be further decomposed. Otherwise, further analysis is possible through pure consonantal and vocalic segments, treated as "fundamental atoms".

A consonantal root is intrinsically modified by vocalic roots.

• pʰair < action root *p "bearing" + class root *h5ih1 "person" + epenthetic *r

Clitic

In Aryan, clitics, similarly to tones, became fossilized as affixes.
