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.
India–Pakistan relations
Apart from Hindustani, India and Pakistan also share a distribution of the Punjabi language (written in the Gurmukhi script in Indian Punjab, and the Shahmukhi script in Pakistani Punjab), Kashmiri language and Sindhi language, mainly due to population exchange. These languages belong to a common Indo-Aryan family that are spoken in countries across the subcontinent.
