West Punjab
At Independence there was a Muslim majority in West Punjab with significant Hindu and Sikh minority. Nearly all of these minorities left West Punjab for India, to be replaced by large numbers of Muslims fleeing from the opposite direction. The official language of West Punjab was Urdu but most of the population spoke Punjabi using the Shahmukhi script. The linguist George Abraham Grierson in his multi volume Linguistic Survey of India (1904–1928) considered the various dialects up to then called "Western Punjabi", spoken in North, West, and South of Lahore in what is now Pakistani Punjab, as constituting instead a distinct language from Punjabi. (The local dialect of Lahore is the Majhi dialect of Punjabi, which has long been the basis of standard literary Punjabi.) Grierson proposed to name this putative language "Lahnda", and he dubbed as "Southern Lahnda" the coherent dialect cluster now known as Saraiki spoken in Multan Dera Ghazi Khan and Bahawalpur division and "North Lahnda" now known as Potwari spoken in Rawalpindi division and "Western Lahnda" now known as Hindko spoken in the regions bordering Khyber-Pakhtunkhwa.
Demographics of Pakistan
Balochi is a provincial language spoken as first language by about 3.5% of Pakistanis, mostly in Balochistan. Sindh and southern Punjab. The name "Balochi" or "Baluchi" is not found before the 10th century. It is believed that the language was brought to its present location in a series of migrations Aleppo, Syria. Rakshani is the major dialect group in terms of numbers. Sarhaddi, is a sub dialect of Rakshani. Other sub – dialects are Qalati, Chagai Kharani, and Makrani. The Eastern Hill Balochi or Northern Balochi are distinct dialects.The Kethran language in North East Balochistan is also a variant of Balochi. It is one of the 9 distinguished languages of Pakistan. Since Balochi is a poetic and rich language and have a certain degree of affinity to Urdu, Balochi poets tend to be very good poets in Urdu as well as Ata Shaad, Gul Khan Nasir and Noon Meem Danish are excellent examples of this.
