Altai: A mountain range in central Asia, rich in the precious metals, is now called in Mongolian Altain ula, "mountain of gold," from ula, "mountain," and altain, genitive of alta, "gold." Al-tai (for Altagh) is the Tartaric form of the name. Hence the name Altaie which is applied to languages of the Mongol-Turkic class.
