Prasun is broken up into three
dialects that are spoken in six villages. The upper dialect, Ṣupu-vari, is spoken in the northernmost village, Ṣupu (Shtive). The central dialect, üšüt-üćü-zumu-vari, is spoken in the middle four villages, Seć (Pronz), Üćü (Dewa), Üšüt (Kshtoki), and Zumu. The lower dialect, Uṣüt-vare, is spoken in Uṣüt (Pashki), the lowest village. For this article, most cited forms will be based on the Seć dialect unless specified otherwise. One characteristic feature defining all Prasun dialects is the shift of ancient
*d to
l, which was lost in intervocalic position in other Nuristani languages, such as
vazala "shoe", compared to
Ashkun vâćâ ,
Kamviri vâćo , and
Nuristani Kalasha oćä , and the pervasive lenition of initial stops, such as
viṭa "wing", compared to
Ashkun pâṭu "feather",
Kamviri pâṭü "feather", and
Nuristani Kalasha paṭä "feather, wing". ==Classification==
