lol okay you sound like you a punjabi nationalist agenda
all languages borrow from each other anways, and so does punjabi; sanskrit is the base of all indo aryan languages including urdu.
Urdu started development in the times of Delhi sultanate at least back in 12th century but progressed into it's present form 300 years ago; Punjabi is not some very old language anyways like urdu, hell there was no Punjab 500 years ago until Mughals carved a province from Sindh Sagar, and then a language from the region began being called Punjabi, the rest of Punjab was later added by conquests of Ranjit Singh such as Waseb and Potohar, even then Punjabi was never official language, even during local rule of Sikhs empire, Farsi was the language of administration, language of elites and lingua franca
It's okay for you to love your first language, it's also my father's language but don't make lies to appease your inner chauvinist.
Fortunately most Punjabis don't have such an attitude towards Urdu, the ones that do probably speak like Sheikh Rasheed
hence the acrimony towards it
