Turkish (Türkçe) is a Turkic language spoken natively in Turkey, Turkish Republic of Northern Cyprus, Bulgaria, as well as by several million immigrants in the European Union. The number of native speakers is uncertain, primarily due to a lack of minority language data from Turkey. The figure of 60 million used here assumes that Turkish is the mother tongue of 80% of the Turkish population, with Kurdish making up most of the remainder. (Linguistic minorities in Turkey are, however, bilingual in Turkish.)

There is a high degree of mutual intelligibility between Turkish and other Oghuz languages such as Azeri, Turkmen, and Qashqai. If these are counted together as "Turkish", the number of native speakers is 100 million, and the total number including second-language speakers is around 125 million.

Classification
Turkish is a member of the Turkish family of languages, which includes Balkan Gagauz Turkish, Gagauz, and Khorasani Turkish in addition to Osmanli Turkish. The Turkish family is a subgroup of the Oghuz languages, themselves a subgroup of the Turkic languages, which most linguists believe to be member of an Altaic language family.

Like Finnish and Hungarian, Turkish has vowel harmony, is agglutinative and has no grammatical gender. Word order is usually Subject Object Verb. Turkish has a T-V distinction: second-person plural forms can be used for individuals as a sign of respect.

Geographic distribution
Turkish is spoken in Turkey and by minorities in 35 other countries. In particular, Turkish is used in countries that formerly (in whole or part) belonged to the Ottoman Empire, such as Bulgaria,Romania, the Former Yugoslav and the Republic of Macedonia.

Official status
Turkish is the official language of Turkey, and is one-although today it is less spoken- of the official languages of Cyprus. It is also an official or national language in Bulgaria.

In Turkey, the Turkish Language Society (Türk Dil Kurumu) was founded by Kemal Atatürk in 1932 as the Türk Dili Tetkik Cemiyeti ("Society for the Investigation of the Turkish Language"), an independent body. In August, 1983, when Turkey was under martial law as a result of the military coup of 1980, the Turkish Language Society was brought under the control of the prime ministry.

Dialects
Dialects of Turkish include Danubian, Eskisehir (spoken in Eskisehir Province), Razgrad, Dinler, Rumelian, Karamanli (spoken in Karaman Province), Edirne (spoken in Edirne), Gaziantep (spoken in Gaziantep Province), Urfa (spoken in Sanliurfa Province), and Goynuk (a village in Bolu).

Replaced old words
When the Turks came from middle Asia to Anatolia about a thousand years ago, they came in contact with Islam and the Arabic societies. Since the Turks accepted Islam, Arabic words (and fewer, Persian words) started infiltrating the language. During the course of over six hundred years of the Ottoman Empire, Turkish kept borrowing loan words from these two languages. Towards the end of the 19th century, this got to a point where the language was rather called the Ottoman language. This is because Turkish had been inundated with so many loan words that the language became a mix of Turkish, Arabic and Persian. In contemporary Turkey, the Ottoman language is almost incomprehensible.

After Atatürk founded the Republic of Turkey, he established the "Turkish Language Foundation" (Türk Dil Kurumu, TDK), whose task was to replace Arabic and Persian origin words with their new Turkish counterparts. The foundation succeeded in removing several hundred Arabic words from the language. While most of the words introduced to the language by TDK are new, TDK also suggested using old Turkish words which had not been used in the language for centuries.

Older and younger people in Turkey tend to express themselves with different vocabulary. While the generations born up to the 1940s tend to use the old Arabic origin words (even the obsolete ones), the younger generations favor using the new expressions. Some new words are not used as often as their old counterparts or have failed to convey the intrinsic meanings of their old equivalents.

Among some of the old words that were replaced are terms in geometry, directions (north, south, east, west), some of the months and many nouns and adjectives. Many new words have also been derived from verbs.

Writing system
Turkish is written using a modified version of the Latin alphabet, which was introduced in 1928 by Kemal Atatürk as part of his efforts to modernize Turkey. Until 1928, Turkish was written using a modified version of the Arabic alphabet (see Ottoman Turkish language), but use of the Arabic alphabet was outlawed after the Latin alphabet was introduced.
