More than 135 million people speak a language from the Turkic family. They range from the Balkans all the way to central Siberia. It is a massive linguistic zone. The traditional view divides these languages into four main groups. There is also one outlier that stands apart.

The Four Main Groups

The Turkic languages split into distinct branches based on geography and history.

Southeastern or Uighur Group
This group includes Uighur. It is spoken mainly in Xinjiang, China. It also includes Uzbek. Uzbek is used in Uzbekistan, other Central Asian republics, and northern Afghanistan.

Southwestern or Oguz Group
The Oguz branch is well known. It includes Turkish. It also covers Azerbaijani (Azeri). You find this language in Azerbaijan and northwestern Iran. Crimean Tatar is part of this group too. It is spoken mostly in Ukraine and Uzbekistan. Turkmen makes up the fourth major language here. It is used in Turkmenistan, northern Iran, and northern Afghanistan.

Northwestern or Kipchak Group
This group is large. It includes Kazakh. People speak Kazakh in Kazakhstan, other Central Asian republics, and western China and Mongolia. Kyrgyz is another key language. It is spoken in Kyrgyzstan, other Central Asian areas, and western China. Tatar is included here as well. Baskhir is spoken in Bashkortostan and adjacent areas in Russia. Karachay-Balkar and Kumyk are found in the Russian Caucasus. Karaim has only a few speakers. They live in Lithuania and parts of southwestern Ukraine.

Northeastern or Altai Group
The Altai group comprises languages and dialects. They are spoken in Siberia northeast of the Irtysh River. They extend into adjacent parts of Mongolia. This includes Altai, Khakas, Shor, and Tuvan. Sakha is also part of this group. It is spoken in the Sakha (Yakutia) republic of Russia and adjacent areas.

The Outlier: Chuvash

Chuvash is distinct. It does not fit neatly into the other groups. It is spoken in Russia’s Chuvash republic and adjacent areas. It stands alone.

Writing Systems and History

The earliest records of Turkic date back to the 8th century. They are funerary inscriptions. They come from northern Mongolia. They use a distinctive writing system called runic script or Turkic runes.

Things changed around 900 CE. The Islamization of nearly all Turkic peoples southwest of the Irtysh began. This shift brought the Arabic alphabet. Turkic languages started adopting it.

Today, the picture is mixed. The Latin alphabet and Cyrillic alphabet are more extensively used. They dominate modern writing.

Which script do you use every day? The answer often depends on where you live. It depends on history. It depends on politics. The spread of these languages is not just about words. It is about power and religion. The runes are quiet now. The Arabic script faded in some places. Latin and Cyrillic took over. But the languages remain. They connect people across vast distances.

The story of Turkic is not finished. It
