Old Tibetan refers to the period of Tibetan language reflected in documents from the adoption of writing by the Tibetan Empire in the mid-7th century to works of the early 11th century.

In 816 CE, during the reign of Sadnalegs, literary Tibetan underwent a thorough reform aimed at standardizing the language and vocabulary of the translations being made from Indian texts, and this resulted in what we now call Classical Tibetan.^[1]
