Punjabi language
Doabi is spoken in both the Indian Punjab as well as parts of Pakistan Punjab owing to post-1947 migration of Muslim populace from East Punjab. The word "Do Aabi" means "the land between two rivers" and this dialect was historically spoken between the rivers of the Beas and the Sutlej in the region called Doaba. Regions it is presently spoken includes the Jalandhar, Hoshiarpur and Kapurthala districts in Indian Punjab, specifically in the areas known as the Dona and Manjki, as well as the Toba Tek Singh and Faisalabad districts in Pakistan Punjab where the dialect is known as Faisalabadi Punjabi.
Punjab, Pakistan
The region was originally called Sapta Sindhu, the Vedic land of the seven rivers flowing into the ocean. The Sanskrit name for the region, as mentioned in the Ramayana and Mahabharata for example, was "Panchanada" which means "Land of the Five Rivers", and was translated to Persian as "Punjab" after the Muslim conquests. The region was known to the Greeks as "Pentapotamia", meaning the region of five rivers. The word "Punjab" was formally introduced in the early 17th century CE as an elision of the Persian words "panj" ("five") and "āb" ("water"), thus meaning the (land of) "five rivers", similar in meaning to the Sanskrit and Greek name for the region. The five rivers, namely Chenab, Jhelum, Ravi, Beas and Sutlej, flow via the Panjnad River into the Indus River and eventually into the Arabian Sea. Of the five great rivers of Punjab, four course through Pakistan's Punjab province.
