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 Hindus
Because the Punjabi Hindus stated Hindi as their mother tongue (due to fear of sikh hegemony as Punjabi Hindus have Punjabi as their first language) in the censuses of 1951 and 1961, after the trifurcation, many areas being mostly Punjabi Hindu were given to Haryana and Himachal Pradesh, which made Punjab a Sikh-majority state in India.
