Tirahi is a nearly extinct Dardic language of the Kohistani group spoken in Afghanistan. According to JSTOR  the speakers of the Tirahi language inhabited the country of Tirah, but there was a feud that broke out between the Tirahi and the Orakzais and Afridis. This feud led the current speakers of Tirahi to move out of Tirah, to Afghanistan. Now there are only about 100 speakers left of this language in Afghanistan.
According to Ethnologue, Tirahi is "nearly extinct" (status 8b). It has been the subject of considerable scholarly attention. George Abraham Grierson was a British linguist who wrote On the Tirahi Language. Another researcher of the Tirahi language is Sir Aurel Stein, an explorer and linguist who composed Notes on Tirahi the Speakers of tirahi, in which he explains that the Tirahi language was at the time spoken in the region between India and Eastern Iran.
