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).
History of the Punjabi language
Middle Indo-Aryan Languages are still synthetic like Old Indo-Aryan Languages but diphthongs and harsh combination of consonants were dropped, so much so that in the literary development these Prakrits became absolutely fluid. One poet said that the difference between Sanskrit poems and Prakrit poems is as great as between man and woman. Sankrit poems are harsh but Prakrit poems are very smooth.In 1837, British East India Company replaced Persian with Urdu in Punjab.
