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.
Languages of Pakistan
Urdu () is the national language (), "lingua franca" and one of two official languages of Pakistan (the other currently being English). Although only about 8% of Pakistanis speak it as their first language, it is widely spoken and understood as a second language by the vast majority of Pakistanis and is being adopted increasingly as a first language by urbanized Pakistanis. It was introduced as the lingua franca upon the capitulation and annexation of Sindh (1843) and Punjab (1849) with the subsequent ban on the use of Persian. According to the linguistic historian Tariq Rahman, however, the oldest name of what is now called Urdu is Hindustani or Hindvi and it existed in some form at least from the 14th century if not earlier (Rahman 2011). It was probably the Indo-Aryan language of the area around Delhi that absorbed words of Persian, Arabic, and Chagatai (a Turkic language)—in a process like the one that created modern English. This language, according to Rahman, is the ancestor of both modern Hindi and Urdu. These became two distinct varieties when Urdu was first Persianized in the 18th century and then Hindi was Sanskritized from 1802 onwards.
