Languages of Pakistan. Pakistan's national language is Urdu, which, along with English, is also the official language. In 2015, the government of Pakistan announced plans to make Urdu the sole official language and abolish English as the second official language. The country is also home to several regional languages, including Punjabi, Saraiki, Pashto, Sindhi, Balochi, Kashmiri, Hindko, Brahui, Shina, Balti, Khowar, Dhatki, Marwari, Wakhi and Burushaski.
The most widely spoken tongue by far is Punjabi, which is the first language of slightly less than half the population. When Saraiki and Hindko, two Punjabi dialects that are sometimes classified as separate languages, are included, well over half of Pakistanis speak Punjabi or a closely related language.
