Punjab
The major language spoken in the Punjab is Punjabi. In the Indian Punjab this is written in the Gurmukhi script. Pakistan uses the Shahmukhi script, that is closer to Urdu script. Hindi, written in the Devanagri script, is used widely in the Indian states of Himanchal Pradesh and Haryana. Several dialects of Punjabi are spoken in the different regions. The Majhi dialect is considered to be textbook Punjabi and is shared by both countries.
Baar di Boli
Also, Bahar Di Boli (Punjabi: ਬਾਹਰ ਦੀ ਬੋਲੀ, باہر دی بولی) means language from outside. In this context it refers to the manner in which Punjabi is spoken outside of India and Pakistan. There is no agreed term relating to how to describe the Diaspora's manner of speaking Punjabi, as it is littered with words mostly from English (to a greater extent, especially nouns, than is Punjabi in Punjab) and occasionally other languages, depending upon where the immigrants ended up. Most came to the West or South East Asia. The Western Punjabis have either settled in Great Britain (the highest concentration anywhere in the world outside of South Asia), Canada, and the States. Commonly the literature written in this type of Punjabi is referred to as Parvasi, which literally means Emigre.
