The term "Oghuz" is applied to the southwestern branch of the Common Turkic languages. It is in reference to the Oghuz Turks, who migrated from the Altai Mountains to Central Asia in the 8th century and further expanded to the Middle East and to the Balkans as separate tribes.

Language classificationEdit

The Oghuz languages currently spoken have been classified into three categories based on their features and geography: Western, Eastern, and Southern.

Proto-Turkic Common Turkic Oghuz

Two further languages, Crimean Tatar and Urum, are Kipchak languages, but have been heavily influenced by the Oghuz languages.

The extinct Pecheneg language was probably Oghuz, but as it is poorly documented, it is difficult to further classify it within the Oghuz family; it is therefore usually excluded from classification.[2]


The Oghuz languages share a number of features that have led linguists to classify them together. Some of the features are shared with other Turkic languages, and others are unique to the Oghuz family.

Shared featuresEdit

Unique featuresEdit

  • Voicing of stops before front vowels (e.g. gör- < kör-, "to see")
  • Loss of q/ɣ after ɯ/u (e.g. quru < quruq, "dry", sarɯ < sarɯɣ, "yellow")
  • Change in form of participial from -gan to -an
