Mongolic is a small, relatively homogenous and recent language family whose common ancestor, Proto-Mongolian, was spoken at the beginning of the second millennium AD.[1][2]
However, Proto-Mongolian seems to descend from a common ancestor to languages like Khitan, which are sister languages of Mongolian languages (they do not descend from Proto-Mongolian but are sister languages from an even older language from the first millennium AD, i.e. Para-Mongolian).[3][4]
The Mongolic language family has about 6 million speakers. The best-known member of this language family, Mongolian, is the primary language of most of the residents of Mongolia and the Mongolian residents of Inner Mongolia, with an estimated 5.2 million speakers.[5]
