Punjabi language
In India, Punjabi is one of the 22 scheduled languages of India. It is the first official language of the Indian State of Punjab. Punjabi also has second language official status in Delhi along with Urdu, and in Haryana. 
In Pakistan, no regional ethnic language has been granted official status at the national level, and as such Punjabi is not an official language at the national level, even though it is the most spoken language in Pakistan after Urdu, the national language of Pakistan. It is, however, the official provincial language of Punjab, Pakistan, the second largest and the most populous province of Pakistan as well as in Islamabad Capital Territory. The only two official national languages in Pakistan are Urdu and English, which are considered the lingua francas of Pakistan.The Majhi (ماجھی ਮਾਝੀ) dialect spoken around Amritsar and Lahore is Punjabi's prestige dialect. Majhi is spoken in the heart of Punjab in the region of Majha, which spans Lahore, Amritsar, Gurdaspur, Kasur, Tarn Taran, Faisalabad, Nankana Sahib, Pathankot, Okara, Pakpattan, Sahiwal, Narowal, Sheikhupura, Sialkot, Chiniot, Gujranwala and Gujrat and in Mandi Bahauddin(97’/.) districts.
Punjab
The region was originally called Sapta Sindhu, the Vedic land of the seven rivers flowing into the ocean. The Sanskrit name for the region, as mentioned in the Ramayana and Mahabharata for example, was "Panchanada" which means "Land of the Five Rivers", and was translated to Persian as "Punjab" after the Muslim conquests. The later name of the region, "Punjab", is a compound of two Persian words, "Panj" (five) and "āb" (water), introduced to the region by the Turko-Persian conquerors of India, and more formally popularised during the Mughal Empire. Punjab thus means "The Land of Five Waters", referring to the rivers Jhelum, Chenab, Ravi, Sutlej, and Beas. All are tributaries of the Indus River, the Chenab being the largest.
