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).

In 1919, Grierson maintained that the dialects of what is now the southwest of Punjab Province in Pakistan constitute a dialect cluster, which he designated "Southern Lahnda" within a putative "Lahnda language". Subsequent Indo-Aryanist linguists have confirmed the reality of this dialect cluster, even while rejecting the name "Southern Lahnda" along with the entity "Lahnda" itself. Grierson also maintained that "Lahnda" was his novel designation for various dialects up to then called "Western Punjabi", spoken north, west, and south of Lahore. The local dialect of Lahore is the Majhi dialect of Punjabi, which has long been the basis of standard literary Punjabi. However, outside of Indo-Aryanist circles, the concept of "Lahnda" is still found in compilations of the world's languages (e.g. Ethnologue).
