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.
Bhojpuri language
Bhojpuri is also spoken by the first generation immigrants who migrated from the UP region which now encompasses parts of Bihar and Uttar Pradesh in India to the newly created Pakistan. It is, however, slowly dying out in Pakistan as the next generation prefers to speak Urdu, Pakistan's national language and lingua franca.
