Cajamarca and Lambayeque Quechua have 94% lexical similarity[1] and are mutually intelligible.
Adelaar (2004) 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,[2] some (Adelaar) believe it to be a primary branch of Quechua II, and others (Landerman, Taylor, Heggarty) analyze it as not straightforwardly classifiable within the traditional QI vs. QII schema at all, and thus potentially a primary branch of its own.
According to the UNESCO World Atlas of Languages in Danger, Cajamarca Quechua is severely endangered.
