Âṣkuňu is a language of Afghanistan spoken by the Ashkun people – also known as the Âṣku, Ashku, Askina, Saňu, Sainu, Yeshkun, Wamas, or Grâmsaňâ – from the region of the central Pech Valley around Wâmâ and in some eastern tributary valleys of the upper Alingar River in Afghanistan's Nuristan province.
Askun is spoken in several dialects in southwestern Nuristan. The main body of the Askunu tribe inhabits the Askugal (Kolata, Majegal) Valley, which drains southwestward into the Alingar River. These people speak a dialect which differs from that of their neighbors in the Titin Valley to the south (cf. Morgenstierne 1929). The inhabitants of the Bajaygol Valley further up the Alingar are reported to speak a third dialect. Across a mountain ridge to the east of the Askunu two tribal groups, each with its own dialect, center on the villages of (Wama) and Gramsaragram (Acanu) off the Pec River.
