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.
Languages of Pakistan
The name Urdu is a short form of 'Zuban-e-Urdu-e-Mualla' i.e. language of the exalted city. In India the term Urdu, although it means 'military camp' in most Turkic languages, was used for the capital city of the king. In other words, the language of the king's capital was a Persianized form of the language known only by its previous and currently less common name Hindustani. This was shortened to 'Urdu' and this term was used for the first time in written records by the poet Mushafi in 1780 (Rahman 2011: 49). It is widely used, both formally and informally, for personal letters as well as public literature, in the literary sphere and in the popular media. It is a required subject of study in all primary and secondary schools. It is the first language of most Muhajirs (Muslim refugees who fled from different parts of India after independence of Pakistan in 1947), who form nearly 8% of Pakistan's population, and is an acquired second language for the rest. As Pakistan's national language, Urdu has been promoted to promote national unity. It is written with a modified form of the Perso-Arabic alphabet—usually in Nastaliq script.
