克丘亞語
The Qulla speak Northwest Jujuy Quechua or Qulla, a dialect of South Bolivian Quechua, which is a variety of Southern Quechua, one of the Quechuan languages. The Qulla of the northern Altiplano near Titicaca, however, appear to have originally spoken the Puquina language, also the likely main language of the Tiwanaku culture during the Middle Horizon period.
