:::I think these the same. Look. From the articles of Tengri, and Tengrism: "Tenger literally means "sky" in Mongolian language and modern Mongolians still pray to "Munkh khukh tenger" ("eternal blue sky"). Therefore Mongolia is called as "land of Eternal Blue Sky ("Munkh khukh tengriin oron" in Mongolian). And also in modern Turkey Tengriism is sometimes called Göktanrı religion by some scholars." I've original wrote it means blue sky in archaic Hungarian with the word "kek", meaning, blue: "kuk tenger" in Mongol, "kök tangri" in Turk, and "kék tenger" in Hungarian, all meaning blu sky. And the other: you just wrote that of z and r Turk-speaking: for i.e.: Dengiz (Tengiz) in z-speak, Tengir in r-speking (in Hungarian i and e, is only a dialectical difference (for example: feher, fehir, is the same, means white), and in these languages the d, t, g are only phonetical, or archaical in some cases (for ie.: gök, kök in Türk) differences. So Dengiz, and Gengiz, Tengiz, Tenger is all the same. In phonetics and linguistics these are logical reasoning so undeniable, I think, so because of these I wrote what I've written. Maybe you can deny or expand it.
