Nepal Lipi is considered the most popular script in Ancient Nepal.
Its popularity is attributed to its simplicity and ease of learning.
In modern times, it is also known as Prachalit Lipi, which literally translates to "Prevalent Script". And also sometimes as Newa Lipi as Newars had a significant role in conservation of this script.
Nepal Lipi is believed to have been used in manuscripts as old as the 10th Century AD and it is found to be used not only in Nepal Bhasa but in Sanskrit, Maithili, Bengali and Hindi as well.
