Afghanistan is a linguistically diverse nation, with more than 40 distinct languages spoken. However, the two official and most widely spoken languages in the country are Dari and Pashto. Dari, also known as Afghan Persian, is the official language of several ethnic groups in the country, including the Tajiks, Hazaras, and Aimaqs, and is the most widely understood language in the country. Pashto is the native tongue of the Pashtuns, the dominant ethnic group in Afghanistan. Other languages spoken in Afghanistan include Uzbeki, Turkmeni, Urdu, Pashai, Nuristani, Arabic, Balochi, and English.

According to a Reddit thread, cricket is mostly popular among Pashtuns, so they speak primarily Pashto, although against Pakistan, they use Dari because many Pakistanis are also Pashtun.
