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.
Punjabis
Punjabis Hindus speak different dialects including Lahnda, as well as Majhi (Standard Punjabi) and others like Doabi and Malwi. Some still have managed to retain the Punjabi dialects spoken in Western Punjab, but many have also adopted Hindi. Punjabi Hindus in India use the Gurmukhi or Nāgarī script to write the Punjabi language.
