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 and Urdu
The Persian language historically influenced many of the modern languages and dialects of the Middle East, Central Asia, Eastern Europe, and South Asia including the standard register Urdu, the national language of Pakistan and an official language in seven states/territories of India. The relationship extends back to around the 3rd millennium BCE, as they both descend from the Proto-Indo-Iranian language.
