Puquina (or Pukina) is a small, putative language family, often portrayed as a language isolate, which consists of the extinct and Kallawaya, although it is assumed that the latter is just a remnant of the former mixed with Quechuan. The Qhapaq simi, which was spoken by the Inca elite, in contrast to the Quechuan-speaking commoners, is thought to be related, as well as, the Leco isolate language. They are spoken by several native ethnic groups in the region surrounding Lake Titicaca (Peru and Bolivia) and in the north of Chile. Puquina itself is often associated with the culture that built Tiwanaku.
