Kawki, a divergent dialect, is spoken in the nearby communities of Cachuy, Canchán, Caipán and Chavín by a few elderly individuals (9 surviving in early 2005). Hardman has noted that while Jaqaru and Kawki share a degree of mutual intelligibility, speakers of one were unable to understand tape recordings of the other, and in a few cases of marriage between Kawki and Jaqaru speakers, the home language was Spanish. (However, the home language of most Jaqaru and Kawki is now Spanish.) Historical analysis shows that the two languages were out of contact for a period. The name Tupe is used for Jaqaru and Kawki together.
