A Turkic language by having a greatest total of speakers is Turkish.

Turkic languages come agglutinative and exhibit phonological vowel harmony.

Though various different Turkic tribes & their languages keep close at hand mixed using esuper more throughout centuries, making the classification highly hard, the very simplified classification can be when follows:

Southwestern languages: (or even Oghuz group) Turkish Turkish, Gagauz, Khorasan Turkic Azerbaijani Azerbaijani, Seljuk, Qashqai, Turkmen Turkmen unclassified Crimean Turkish of Central Asia, Urum, Salar Northwestern languages: (or even Kypchak group) Aralo-Caspian: Kazakh, Kyrgyz, Karakalpak, Nogai Ponto-Caspian: Karachay-Balkar, Kumyk, Karaim, Krymchak (Judeo-Crimean Tatar), Pecheneg (extinct), Cuman (extinct) Uralian: Tatar, , Bashkir, Chulym Northern languages: Siberian class action: Altai, ** Yellow Uighur Eastern languages: Uighur-Chagatai (or even Karluk) group: Uzbek, Uighur, Chagatai (extinct) Khalaj Oghuric (or Hunnic) languages (or so-supposed "Lir Turkic"; another time considered to exist as the separate Altaic subfamily) Proto-Bulgar Chuvash, Bolgar (extinct & a inclusion of Bolgar in the Turkic language group is disputed), Khazar (extinct) Various elements own passed to Turkic languages especially from either Chinese, Persian, Russian and Arabic languages, & various elements from either Turkic languages keep around been carried when far when a northmost territories of Russia, and possibly even to N United states of america. Notwithstanding, these are probably that a Arctic peoples (differently the Dolgans & a Yakuts), although perchance however belonging to a greater Altaic supraclass action, actually form a different linguistic group distinct from either the Turkic languages. Compare this to the Koreans or Japanese peoples, for instance.
