what language do they speak in kabul afghanistan

In Kabul, the primary languages you'll hear spoken by almost everyone are Dari and Pashto. They're the official languages of the country, and most folks in the capital are actually bilingual. Dari serves as the main language for government, business, and everyday communication among the city's diverse population, so it's the one you'll encounter the most if you're walking through the markets or grabbing tea.

I’ve always found the linguistic landscape there super interesting because of how deep the history goes. While Dari is the lingua franca, Pashto is also very common since a lot of people have moved to the city from different provinces over the years. You might also run into people who speak a bit of English, especially the younger generation, but sticking to Dari will definitely get you much further if you're trying to connect with the locals.
