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).
Punjabi nationalism
Beside the fact that, in 1800 century, religious ratio of Punjabi people in Punjab was 48% Muslim Punjabis, 43% Hindu Punjabis, 8% Sikh Punjabis and 1% others, but due to attraction of the various tribes, castes and the inhabitants of the Punjab into a broader common "Punjabi" identity and uniting by natural affinity of "Punjabi Nationalism", Punjab was a secular regime, Punjabi was a secular nation and after throwing out the Muslim Mughal invaders of Punjab from Delhi, India and Muslim Afghan invaders of Punjab from Kabul, Afghanistan, a Sikh Punjabi, Maharaja Ranjit Singh was the ruler of Punjab, which provided the boost to the already initiated Punjabi nationalism.
