Chechen language
Chechen ( , ) is a Northeast Caucasian language spoken by more than 1.4 million people, mostly in the Chechen Republic and by members of the Chechen diaspora throughout Russia, Jordan, Central Asia (mainly Kazakhstan and Kyrgyzstan), and Georgia.
Koban culture
Amjad Jaimoukha argues that while all these cultures probably were made by people included among the genetic ancestors of the Northern Caucasian Nakh (i.e. Chechens and Ingush), it was either the Koban or Kharachoi culture that was the first culture made by the cultural and linguistic ancestors of the Chechens (meaning the Chechens first arrived in their homeland 3000–4000 years ago). Johanna Nichols has written that "There is fairly seamless archeological continuity for the last 8000 years or more in central Daghestan, suggesting that the Nakh-Daghestanian language family is long indigenous."
