I've heard that forms of Turkish are spoken as far east as Western China. A few words that I've heard are really close to Chinese...like "su" for water is ~really~ close to the word in Cantonese.

In my case;


Turkish language is belong to the Altaic branch of the Ural-Altaic family of languages.Like the other UraliAfter the waning of the Gokturk state, the Uighurs produced many written texts that are among the most important source works for the Turkish language. The Uighurs abandoned shamanism (the original Turkish religion) in favor of Buddhism, Manichaeanism and Brahmanism, and translated the pious and philosophical works into Turkish. Examples are Altun Yaruk, Mautrisimit, Sekiz Yükmek, Huastunift. These are collected in Turkische Turfan-Texte. The Gokturk inscriptions, together with Uighur writings, are in a language called by scholars Old Turkish.

Turkish was written in the Arabic script < the trick is Turks have never spoken arabic, they'd just used their scripts in writing > following the conversion of the Turks to Islam.

The Turkish that developed in Anatolia and Balkans in the times of the Seljuk’s and Ottomans is documented in several literary works prior to the 13th century. The men of letters of the time were, notably, Sultan Veled, the son of Mevlana Celaleddin-i Rumi, Ahmed Fakih, Seyyad Hamza, Yunus Emre, a prominent thinker of the time, and the famed poet, Gulsehri. This Turkish has a dialect which falls into the southwestern dialects of the Western Turkish language family and also into the dialects of the Oguz Türkmen language group. When the Turkish spoken in Turkey is considered in a historical context, it can be classified according to three distinct periods:

1. Old Anatolian Turkish (old Ottoman - between the 13th and the 15th centuries)

2. Ottoman Turkish (from the 16th to the 19th century)

3. 20th century Turkish

With the proclamation of the Republic in 1923 and after the process of national integration in the 1923-1928 period, the subject of adopting a new alphabet became an issue of utmost importance. Mustafa Kemal Atatürk had the Latin alphabet adapted to the Turkish vowel system, believing that to reach the level of contemporary civilization, it was essential to benefit from western culture. The creation of the Turkish Language Society in 1932 was another milestone in the effort to reform the language.

In addition, maybe the pronunciation might be similar, because turkish history rised in middle asia. But the alphabet and language culture are preety different between eachother.

Well...there are different dialects of the Turkish language like in Uzbekistan, Azerbajian, etc. So, I have been told that people from Turkey who travel to those Central Asian countries can often understand the people there and vice versa because a lot of the words are very similar.
I was told the same about Japanese and Turkish coming from the same linguistic family. Very interesting...would have never guessed that. Same as...oh, what was the other one I was told..Dutch? No, I think I am way off...
Anybody who knows, tell me or it will be bugging me all night!
