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.
Punjabi language
Punjabi is unusual among Indo-European languages in its use of lexical tone (that is, the way in which the pitch of the voice conveys meaning). The Punjabi language is written in one of two alphabets: Shahmukhi or Gurmukhi. In the Punjab, both writing systems are used (a rare occurrence called synchronic digraphia): Shahmukhi is used mainly by Punjabi Muslims, and Gurmukhi is used mainly by Punjabi Sikhs and Hindus.
