Cajamarca–Cañaris Quechua

Cajamarca–Cañaris Quechua is a branch of Quechua spoken in northern Peru, consisting primarily of Cajamarca Quechua, and Lambayeque Quechua, spoken in the Cajamarca and Lambayeque regions near the towns of Cajamarca and Cañaris. Cajamarca and Lambayeque Quechua share 94% lexical similarity and are mutually intelligible. Adelaar includes the dialect of Lincha District, far to the south on the border of the Lima and Huancavelica regions.
Cajamarca–Cañaris Quechua is divergent from other varieties; although traditionally classified as a member of Quechua II-A, some believe it to be a primary branch of Quechua II, and others analyze it as not straightforwardly classifiable within the traditional QI vs. QII schema at all, and thus potentially a primary branch of its own. Félix Quesada published the first grammar and dictionary in 1976.
According to the UNESCO World Atlas of Languages in Danger, Cajamarca Quechua is severely endangered.
