Mongolian writing systems
Various Mongolian writing systems have been devised for the Mongolian language over the centuries, and from a variety of scripts. The oldest and native script, called simply the Mongolian script, has been the predominant script during most of Mongolian history, and is still in active use today in the Inner Mongolia region of China and has de facto use in Mongolia.
