Dari is the conservative, courtly cousin of modern Iranian Persian, rooted in ancient history.

In short: Often called Afghan Persian, Dari is the official language of Afghanistan and a vital lingua franca. While mutually intelligible with Iranian Persian, it preserves ancient phonological features that have shifted in Iran. From the Sassanid court to the Mughal Empire, Dari has shaped culture across Central and South Asia.

Dari, or Afghan Persian, is one of two official languages in Afghanistan alongside Pashto. While the term 'Dari' was officially adopted by the Afghan government in 1964 for political state-building, the language itself is a direct continuation of Middle Persian, the administrative and religious language of the Sassanid Empire (224–651 AD). This lineage traces back further to the Old Persian of the Achaemenids (550–330 BC). Historically, 'Dari' referred to the court language of the Sassanids, with the name likely deriving from 'dar' or 'darbar', meaning 'court'.

The language is remarkably conservative compared to the standard Iranian Persian register. While Iranian Persian has undergone significant shifts—such as the merging of certain vowels and the adoption of a labiodental 'v' sound—Dari maintains distinctions found in Classical Persian. For example, Dari keeps the 'majhul' and 'ma'ruf' vowel pairs separate, and retains the classical bilabial 'w' pronunciation. These features make Dari phonologically closer to Tajiki Persian than to the dialect of Tehran.

Beyond its role in Afghanistan, where it serves as a lingua franca for up to 78% of the population, Dari was the prestigious administrative and literary language of the Mughal Empire. Its influence is embedded in many Indo-Aryan languages, including Hindi, Urdu, and Bengali. Common English loanwords like 'pyjama' and 'dopiaza' reflect the specific Afghan Persian pronunciation rather than the Iranian variant. Today, the Kabuli dialect serves as the standard model for Dari, a status solidified by decades of broadcasting on Radio Afghanistan since the 1940s.

The language landscape in Afghanistan is diverse, with researchers identifying distinct dialect groups. The Southeastern group, centered around Kabul, is noted for its conservative nature, while Western dialects like Herati show closer ties to the Persian spoken in eastern Iran. Despite these regional variations, Dari remains a unifying force, bridging ethnic divides and preserving a rich literary tradition that stretches from the works of Rumi to the poetry of the Timurid era.
