The Turkic languages constitute a language family of at least thirty-five^[1] languages, spoken by Turkic peoples across a vast area from Eastern Europe and the Mediterranean to Siberia and Western China, and are considered to be part of the proposed Altaic language family.^[2][3]

Turkic languages are spoken as a native language by some 165^[4] to 200 million people;^[5] and the total number of Turkic speakers is over 300 million, including speakers of a second language. The Turkic language with the greatest number of speakers is Turkish proper, or Anatolian [and Balkan] Turkish, the speakers of which account for about 40% of all Turkic speakers.^[3]

Characteristic features of Turkish, such as vowel harmony, agglutination, and lack of grammatical gender, are universal within the Turkic family.^[3] There is also a high degree of mutual intelligibility between the various Oghuz languages, which include Turkish, Azerbaijani, Turkmen, Qashqai, Gagauz, Balkan Gagauz Turkish and Oghuz influenced Crimean Tatar.^[6]

Characteristics[link]

The characteristic features of the Turkic languages are vowel harmony, extensive agglutination by means of suffixes and other affixes, and lack of noun classes or grammatical gender. Subject–object–verb word order is universal within the family. All of these distinguishing characteristics are shared with the Mongolic, Tungusic, and Korean language families, as well as (with the exception of vowel harmony) with Japonic, which are considered by some linguists to be genetically linked with the Turkic languages in an Altaic language family.^[7][8]

History[link]

The geographical distribution of Turkic-speaking peoples across Eurasia ranges from the North-East of Siberia to Turkey in the West (see picture in the box on the right above).^[9]

Early written records[link]

The first established records of the Turkic languages are the eighth century 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 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.^[10]

The Codex Cumanicus (12th–13th centuries) 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.

Geographical expansion and development[link]

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

This section requires expansion.

Classification[link]

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.^[12] 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)^[13] and are mainly based on the development of *d. However, there are still many questions for which ongoing research has not yet found an adequate solution.

The Turkic languages may be divided into six branches (Johanson 1998):^[14]

1. Southwestern (Oghuz Turkic)
2. Northwestern (Kipchak Turkic)
3. Southeastern (Uyghur Turkic)^[15]
4. Northeastern (Siberian Turkic)
5. Oghur Turkic
6. Arghu 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.^[16]

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.^[17]

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.

Schema[link]

The following isoglosses are traditionally used in the classification of the Turkic languages:^[14]

• Rhoticisation, e.g. in the last consonant of the word for "nine" *toqqız. This separates the Oghur branch, which exhibits /r/, from the rest of Turkic, which exhibits /z/. In this case, rhoticisation refers to the development of *-/r/, *-/z/, and *-/d/ to /r/ in this branch.^[18]
• Intervocalic *d, e.g. the second consonant in the word for "foot" *hadaq
• Word-final -G, e.g. in the word for "mountain" *tāğ
• Suffix-final -G, e.g. in the suffix *lIG, in e.g. *tāğlığ

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", *ań

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

Vocabulary comparison[link]

This section needs attention from an expert on the subject. Please add a reason or a talk parameter to this template to explain the issue with the section. Consider associating this request with a WikiProject. (November 2010)

The following is a brief comparison of cognates among the basic vocabulary across the Turkic language family (about 60 words).

Empty cells do not necessarily imply that a particular language is lacking a word to describe the concept, but rather that the word for the concept in that language may be formed from another stem and is not a cognate with the other words in the row or that the equivalent was unknown to contributors to this article.

Also, there may be shifts in the meaning from one language to another, and so the "Common meaning" given is only approximate. In some cases the form given is found only in some dialects of the language. Forms are given in native Latin orthographies unless otherwise noted.
