Punjabis
The main language of the Punjabi people is Punjabi and its associated dialects, which differ depending on the region of Punjab the speaker is from; there are notable differences in the Lahnda languages, spoken in the Pakistani Punjab. In the Pakistani Punjab, the vast majority still speak Punjabi, even though the language has no governmental support. In the Indian Punjab, most people speak Punjabi. English is sometimes used, and older people who lived in the undivided Punjab may be able to speak and write in Urdu. The Punjabi languages have always absorbed numerous loanwords from surrounding areas and provinces (and from English).
Persian language in the Indian subcontinent
The Persian language in the Indian subcontinent, before the British colonized the Indian subcontinent, was the region's lingua franca and a widely used official language. The language was brought into the Indian subcontinent by various Turkic and Afghan dynasties, in particular the Turko-Afghan Delhi Sultanate and the Mughal Dynasty. Persian held official status in the court and the administration within these empires and it heavily influenced many of the local languages, particularly the Urdu dialect of Hindustani.
