Kaskian (Kaskean) was the language of the Kaskians (Kaska) of northeastern Bronze Age Anatolia in the mountains along the Black Sea coast.
It is sometimes suspected that Kaskian was related to the pre-Hittite Hattic language, based on toponyms and personal names; the Hattic moon god was named Kasku.
[3] There may also be connections to the Northwest Caucasian languages; the name Kaskian[4] may be cognate with an old name for Circassia,[5] and the name of one of the tribes in the Kaskian confederation, the Abešla, may be cognate with the endonym of the Abkhaz people and some Circassian people,[6] suggesting the Kaskians proper and Abešla might have been the ancestors of the Circassians and other Caucasian peoples.
[7] It has been conjectured that Kaskian might belong to the Zan family of languages, and have affinities to Megrelian or Laz.
[8] In 2023, D. Sasseville presented an unknown language preserved on several tablet fragments from the archives of Hattusa and argued on methodological grounds that it is the Kaskean language.
