The Prasuni Alphabet

No. Prasuni is primarily an oral language with no traditional native writing system. The language has been transmitted exclusively through speech and oral tradition in the Prasun Valley of Nuristan for centuries.

For academic and linguistic documentation, scholars use a Latin-based romanization system — primarily the one developed by Georg Morgenstierne during his fieldwork in the 1920s–1960s. This system uses diacritical marks to represent sounds absent from standard European languages: macrons (ā, ī, ū) for long vowels, and dots below (ṭ, ḍ, ṣ, ṇ) for retroflex consonants.

In everyday life, Prasuni speakers who are literate typically write in Dari (Afghan Persian) using the Perso-Arabic script, as Dari is the primary language of education and government in Afghanistan.

Prasuni belongs to the Nuristani branch of the Indo-Iranian sub-family of the Indo-European language family. Nuristani is the third primary branch of Indo-Iranian — distinct from both the Indo-Aryan branch (Sanskrit, Hindi, Urdu, Bengali) and the Iranian branch (Persian, Kurdish, Pashto, Balochi).

Within Nuristani, Prasuni belongs to the Eastern Nuristani sub-group, most closely related to Ashkun (spoken in the Waygal Valley). Other Nuristani languages include Kati (the largest), Waigali, and Tregami.

Nuristani languages are significant for Indo-European linguistics because they preserve ancient features — such as retroflex consonants and aspirated stops — lost in both Iranian and Indo-Aryan branches.

Prasuni is spoken in the Prasun Valley (also called the Pâṣai Valley) in Nuristan Province, northeastern Afghanistan. The valley is located in the remote Hindu Kush mountains and is one of the most isolated language communities in all of Nuristan.

Nuristan Province borders Kunar and Laghman provinces to the south and west, and Pakistan's Chitral District to the east. The geographic isolation of the Prasun Valley has helped preserve the language and its archaic Indo-European features.

The total speaker population of Prasuni is estimated at approximately 2,000–3,000 people — making it among the smallest surviving Nuristani languages. Prasuni is sometimes referred to by its speakers as Präsun or by the name of the valley, Pâṣai.

Prasuni is one of several Nuristani languages spoken in Nuristan Province, Afghanistan. The Nuristani group includes Kati (the largest, spoken in Bashgal Valley), Ashkun (Waygal Valley), Waigali (Waigal Valley), Tregami, and Prasuni itself.

Prasuni is most closely related to Ashkun within the Eastern Nuristani sub-group. Both languages share the characteristic retroflex consonants, aspirated stops, and vowel length contrasts that define the Nuristani branch. Kati is more distantly related, belonging to a separate sub-group.

All Nuristani languages share the same ancient origin and were formerly called "Kafiri" languages. After the region was renamed Nuristan in 1896, the languages adopted the designation "Nuristani" in academic literature.

Yes. Prasuni is classified as Severely Endangered by the Endangered Languages Project and is considered among the most at-risk languages in South Asia. With only an estimated 2,000–3,000 speakers, it has one of the smallest speaker populations among Nuristani languages.

Several factors threaten the language: formal education in Nuristan is conducted in Dari and Pashto rather than Prasuni; decades of conflict (Soviet-Afghan War, civil war, Taliban era, post-2001 period) have disrupted communities and forced displacement; and the remoteness of the Prasun Valley limits access to language documentation resources.

Academic documentation by Georg Morgenstierne and subsequent scholars has preserved significant linguistic data, but no standardised written form or active literacy programme exists for Prasuni.

Prasuni uses a Latin-based academic romanization rather than a native script, which means its written form is a scholarly convention rather than a community writing system. The romanization was developed by Georg Morgenstierne for documenting Nuristani languages in the 1920s–1960s and uses several special characters not found in standard Latin.

The most distinctive features are: macrons (ā, ī, ū, ē, ō) to mark phonemically long vowels; dots below consonants (ṭ, ḍ, ṣ, ṇ) to mark retroflex sounds; diacritical letters (š for "sh", ž for "zh", č for "ch"); and the gamma character (γ) for the voiced velar fricative.

These conventions are consistent across Nuristani language documentation and allow linguists to precisely represent the phonological distinctions unique to this language family.
