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.
Bazigar language
The Bazigar language is the Dravidian language of the Bazigar, a group of traveling acrobats of the Punjab region. Speakers are scattered across the country, but the principal block of speakers are south of Chandigarh in adjoining areas of the states of Panjab, Haryana, and Uttar Pradesh. Speakers are shifting to more dominant languages. Although Ethnologue classifies it as Dravidian, Bazigar has significant lexical similarity with Punjabi, as well as influence from western Rajasthani dialects. Bazigar has an almost identical phonology to Punjabi except for the presence of the voiceless palatal fricative and the absence of the voiceless glottal fricative.
