Nepali, also known as Khas-Kura, is the official language of Nepal and is spoken by the majority of the population. It is written in the Devanagari script and belongs to the Indo-Aryan branch of the Indo-European language family.
The development and expansion of the Nepali language can be traced back to the ancient Kingdom of Nepal, which was established in the early 18th century. At that time, the language was known as Khas-Kura and was spoken by the Khas people, who lived in the western part of Nepal. Over time, Khas-Kura spread to other parts of the country and was eventually adopted as the official language of Nepal.
In the 20th century, Nepali underwent further expansion and development as the country underwent political and social changes. During this time, the language was used as a means of unifying the diverse ethnic groups within Nepal and promoting national identity.
Today, Nepali is spoken by a large portion of the population in Nepal and is also used as a lingua franca in parts of India and Bhutan. It is taught in schools and is used in the media, government, and other areas of public life. The expansion and development of the Nepali language have played a significant role in the cultural and political history of Nepal.
