The forms of the name "Tengri" () among the ancient and modern Turks and Mongols are "Tengeri", "Tangara", "Tangri", "Tanri", "Tangre", "Tegri", "Tingir", "Tenkri", "Teri", "Ter", and "Ture". The name Tengri ("the Sky") is derived from ("daybreak") or Tan ("dawn"). Meanwhile, Stefan Georg proposed that the Turkic "Tengri" ultimately originates as a loanword from Proto-Yeniseian "*tɨŋgVr-" "high". Mongolia is sometimes poetically called the "Land of Eternal Blue Sky" () by its inhabitants. According to some scholars, the name of the important deity Dangun (also Tangol) (God of the Mountains) of the Korean folk religion is related to the Siberian "Tengri" ("Heaven"), while the bear is a symbol of the Big Dipper (Ursa Major).
