Punjabi language
Punjabi developed from Sanskrit through Prakrit languages and later (Sanskrit: ; corruption or corrupted speech) From 600 BC Sanskrit gave birth to many regional languages in different parts of India. All these languages are called Prakrit (Sanskrit: ) collectively. Shauraseni Prakrit was one of these Prakrit languages, which was spoken in north and north-western India and Punjabi and western dialects of Hindi developed from this Prakrit. Later in northern India Shauraseni Prakrit gave rise to Shauraseni Aparbhsha, a descendent of Prakrit. Punjabi emerged as an Apabhramsha, a degenerated form of Prakrit, in the 7th century A.D. and became stable by the 10th century. By the 10th century, many Nath poets were associated with earlier Punjabi works.
