Tirahi
Tirahi是印欧语系的一种语言，过去分布在阿富汗，现已消亡。
Tirahi is a nearly extinct if not already extinct Indo-Aryan language spoken in a few villages in the southeast of Jalalabad in the Nangarhar Province of eastern Afghanistan. It is spoken by older adults, who are likewise fluent in Pashto.
The Tirahis were expelled from Tirah in the present-day Khyber District of Khyber Pakhtunkhwa, Pakistan, by the Afridi Pashtuns. Georg Morgenstierne claimed that Tirahi is "probably the remnant of a dialect group extending from Tirah through the Peshawar district into Swat and Dir."
