Punjabi culture
The culture of the Punjab encompasses the spoken language, written literature, cuisine, science, technology, military warfare, architecture, traditions, values and history of the Punjabi people native to the northern part of the Indian subcontinent. The term 'Punjabi' can mean both a person who lives in Punjab and also a speaker of the Punjabi language. This name originates from the Persian language 'panj', (five), and 'ab', (water). Combined together the word becomes Panjab or Punjab: land of the five rivers. Indus River (the largest river in this five river system), and the five other rivers to the south eventually join Indus or merge into it later in the downstream of the Punjab valley. All the rivers start and flow out of the Himalayas. These other five rivers are Jhelum River, Chenab River, Ravi River, Beas River and Sutlej River.
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.
