Turkic languages

The homeland of the Turkic peoples and their language is suggested to be somewhere between the Transcaspian steppe and Northeastern Asia (Manchuria),[16] with genetic evidence pointing to the region near South Siberia and Mongolia as the "Inner Asian Homeland" of the Turkic ethnicity.[17] Similarly several linguists, including Juha Janhunen, Roger Blench and Matthew Spriggs, suggest that modern-day Mongolia is the homeland of the early Turkic language.[18]

Extensive contact took place between Proto-Turks and Proto-Mongols approximately during the first millennium BC; the shared cultural tradition between the two Eurasian nomadic groups is called the "Turco-Mongol" tradition. The two groups shared a similar religion-system, Tengrism, and there exists a multitude of evident loanwords between Turkic languages and Mongolic languages. Although the loans were bidirectional, today Turkic loanwords constitute the largest foreign component in Mongolian vocabulary.[19]

Some lexical and extensive typological similarities between Turkic and the nearby Tungusic and Mongolic families, as well as the Korean and Japonic families (all formerly widely considered to be part of the so-called Altaic language family) has in more recent years been instead attributed to prehistoric contact amongst the group, sometimes referred to as the Northeast Asian sprachbund. A more recent (circa first millennium BCE) contact between "core Altaic" (Turkic, Mongolic, and Tungusic) is distinguished from this, due to the existence of definitive common words that appear to have been mostly borrowed from Turkic into Mongolic, and later from Mongolic into Tungusic, as Turkic borrowings into Mongolic significantly outnumber Mongolic borrowings into Turkic, and Turkic and Tungusic do not share any words that do not also exist in Mongolic.

Alexander Vovin (2004, 2010)[20][21] notes that Old Turkic had borrowed some words from the Ruan-ruan language (the language of the Rouran Khaganate), which Vovin considers to be an extinct non-Altaic language that is possibly a Yeniseian language or not related to any modern-day language.

Turkic languages also show some Chinese loanwords that point to early contact during the time of proto-Turkic.[22]

Robbeets (et al. 2015 and et al. 2017) suggest that the homeland of the Turkic languages was somewhere in Manchuria, close to the Mongolic, Tungusic and Koreanic homeland (including the ancestor of Japonic), and that these languages share a common "Transeurasian" origin.[23] More evidence for the proposed ancestral "Transeurasian" origin was presented by Nelson et al. 2020 and Li et al. 2020.[24][25]

10th-century Irk Bitig or "Book of Divination" written in Old Uyghur language with the Orkhon script

The first established records of the Turkic languages are the eighth century AD Orkhon inscriptions by the Göktürks, recording the Old Turkic language, which were discovered in 1889 in the Orkhon Valley in Mongolia. The Compendium of the Turkic Dialects (Divânü Lügati't-Türk), written during the 11th century AD by Kaşgarlı Mahmud of the Kara-Khanid Khanate, constitutes an early linguistic treatment of the family. The Compendium is the first comprehensive dictionary of the Turkic languages and also includes the first known map of the Turkic speakers' geographical distribution. It mainly pertains to the Southwestern branch of the family.[26]

The Codex Cumanicus (12th–13th centuries AD) concerning the Northwestern branch is another early linguistic manual, between the Kipchak language and Latin, used by the Catholic missionaries sent to the Western Cumans inhabiting a region corresponding to present-day Hungary and Romania. The earliest records of the language spoken by Volga Bulgars, the parent to today's Chuvash language, are dated to the 13th–14th centuries AD.

With the Turkic expansion during the Early Middle Ages (c. 6th–11th centuries AD), Turkic languages, in the course of just a few centuries, spread across Central Asia, from Siberia to the Mediterranean. Various terminologies from the Turkic languages have passed into Persian, Hindustani, Russian, Chinese, and to a lesser extent, Arabic.[27]

The geographical distribution of Turkic-speaking peoples across Eurasia since the Ottoman era ranges from the North-East of Siberia to Turkey in the West.[28] (See picture in the box on the right above.)

For centuries, the Turkic-speaking peoples have migrated extensively and intermingled continuously, and their languages have been influenced mutually and through contact with the surrounding languages, especially the Iranian, Slavic, and Mongolic languages.[29]

This has obscured the historical developments within each language and/or language group, and as a result, there exist several systems to classify the Turkic languages. The modern genetic classification schemes for Turkic are still largely indebted to Samoilovich (1922).

The Turkic languages may be divided into six branches:[30]

• Common Turkic
  • Southwestern (Oghuz Turkic)
  • Southeastern (Karluk Turkic)
  • Northwestern (Kipchak Turkic)
  • Northeastern (Siberian Turkic)
  • Arghu Turkic
• Oghur Turkic

In this classification, Oghur Turkic is also referred to as Lir-Turkic, and the other branches are subsumed under the title of Shaz-Turkic or Common Turkic. It is not clear when these two major types of Turkic can be assumed to have actually diverged.[31]

With less certainty, the Southwestern, Northwestern, Southeastern and Oghur groups may further be summarized as West Turkic, the Northeastern, Kyrgyz-Kipchak and Arghu (Khalaj) groups as East Turkic.[32]

Geographically and linguistically, the languages of the Northwestern and Southeastern subgroups belong to the central Turkic languages, while the Northeastern and Khalaj languages are the so-called peripheral languages.

Hruschka, et al. (2014)[33] use computational phylogenetic methods to calculate a tree of Turkic based on phonological sound changes.

The following isoglosses are traditionally used in the classification of the Turkic languages:[34][30]

• Rhotacism (or in some views, zetacism), e.g. in the last consonant of the word for "nine" *tokkuz. This separates the Oghur branch, which exhibits /r/, from the rest of Turkic, which exhibits /z/. In this case, rhotacism refers to the development of *-/r/, *-/z/, and *-/d/ to /r/,*-/k/,*-/kh/ in this branch.[35] See Antonov and Jacques (2012) [36] on the debate concerning rhotacism and lambdacism in Turkic.
• Intervocalic *d, e.g. the second consonant in the word for "foot" *hadaq
• Suffix-final -G, e.g. in the suffix *lIG, in e.g. *tāglïg

Additional isoglosses include:

• Preservation of word initial *h, e.g. in the word for "foot" *hadaq. This separates Khalaj as a peripheral language.
• Denasalisation of palatal *ń, e.g. in the word for "moon", *āń

*In the standard Istanbul dialect of Turkish, the ğ in dağ and dağlı is not realized as a consonant, but as a slight lengthening of the preceding vowel.

The following table is based upon the classification scheme presented by Lars Johanson (1998)[37]

The possibility of a genetic relation between Turkic and Korean, independently from Altaic, is suggested by some linguists.[45][46][47] The linguist Kabak (2004) of the University of Würzburg states that Turkic and Korean share similar phonology as well as morphology. Yong-Sŏng Li (2014)[46] suggest that there are several cognates between Turkic and Old Korean. He states that these supposed cognates can be useful to reconstruct the early Turkic language. According to him, words related to nature, earth and ruling but especially to the sky and stars seem to be cognates.

The linguist Choi[47] suggested already in 1996 a close relationship between Turkic and Korean regardless of any Altaic connections:

In addition, the fact that the morphological elements are not easily borrowed between languages, added to the fact that the common morphological elements between Korean and Turkic are not less numerous than between Turkic and other Altaic languages, strengthens the possibility that there is a close genetic affinity between Korean and Turkic.

Many historians also point out a close non-linguistic relationship between Turkic peoples and Koreans.[48] Especially close were the relations between the Göktürks and Goguryeo.[49]

Some linguists suggested a relation to Uralic languages, especially to the Ugric languages. This view is rejected and seen as obsolete by mainstream linguists. Similarities are because of language contact and borrowings mostly from Turkic into Ugric languages. Stachowski (2015) states that any relation between Turkic and Uralic must be a contact one.[50]
