The Mongolian languages are a group of languages spoken primarily in Mongolia and parts of China, particularly in the Inner Mongolia region. The most widely spoken language is Khalkha Mongolian, which serves as the official language of Mongolia. Other languages in this group include Buryat and Oirat, each with its own dialects and variations. These languages belong to the Mongolic language family, which is part of the larger Altaic language family. Mongolian languages are characterized by their use of vowel harmony and agglutinative structure, meaning they often form words by adding prefixes and suffixes to a root.
