Kohāṭī is a Hindko dialect of Kohat District, Khyber Pakhtunkhwa, north-western Pakistan. It is spoken in the city of Kohat as well as in a string of villages running east along the road to Kushalgarh on the Indus. The dominant language of this area is Pashto, to which Kohati has been losing ground at least since Partition. Kohati forms part of the "Hindko proper" group of dialects alongside Awankari, Chacchi and Ghebi.
It has borrowed words from Pashto to a higher extent than other Hindko dialects. A lexical similarity study based on a 210-item wordlist found out that it shares 79% of its vocabulary with the Hindko dialect spoken to the east in the city of Attock, and 76% each with the dialects further east in Talagang Tehsil and Haripur District, as well as the rural dialect spoken immediately north in Peshawar District.
