Afghanistan is a linguistically diverse nation with upwards of 40 distinct spoken languages. Dari and Pashto serve as the two main official languages. Dari, historically serving as the region’s lingua franca, is a shared language between the country's different ethnic groups. While Pashto is the dominant first language in the southern and eastern regions of the country, but is primarily spoken within its own ethnic lines.
The country's two main official languages, Dari and Pashto are also sister languages, as both are Iranian languages and are part of the larger Indo-European languages family. The third largest language, Uzbek, is a Turkic language and is sister to neighboring Turkmen. The Turkic languages, along with Balochi, Pashayi, Nuristani, and Pamiri, are the third official languages in areas where the majority speaks them.
