Macro-Arawakan is a proposed language family of South America and the Caribbean centered on the Arawakan languages. Sometimes, the proposal is called Arawakan, and the central family is called Maipurean.
Aymaran is one of the two dominant language families in the central Andes alongside Quechuan. The family consists of Aymara, widely spoken in Bolivia, and the endangered Jaqaru and Kawki languages of Peru.
Mochica is an extinct language formerly spoken along the northwest coast of Peru and in an inland village. First documented in 1607, the language was widely spoken in the area during the 17th century and the early 18th century. By the late 19th century, the language was dying out and spoken only by a few people in the village of Etén, in Chiclayo. It died out as a spoken language around 1920, but certain words and phrases continued to be used until the 1960s.
The Araucanian languages are a small language family of indigenous languages of the Americas spoken in central Chile and neighboring areas of Argentina. The living representatives of this family are Mapudungun and Huilliche, spoken respectively by the Mapuche and Huilliche people. These are usually considered divergent dialects of a single language isolate.
Munichi is an extinct language which was spoken in the village of Munichis, about 10 miles (16 km) west of Yurimaguas, Loreto Region, Peru. In 1988, there were two mother-tongue speakers, but they had not met since the 1970s. The last known fluent speaker, Victoria Huancho Icahuate, died in the late 1990s. As of 2009 there were several semi-speakers who retained significant lexical, and partial grammatical, knowledge of the language.
Pano-Tacanan is a proposed family of languages spoken in Peru, western Brazil, Bolivia and northern Paraguay. There are two close-knit branches, Panoan and Tacanan, with 33 languages. There are lexical and grammatical similarities between the two branches, but it has not yet been demonstrated that these are genetic.
Yuracaré is an endangered language isolate of central Bolivia in Cochabamba and Beni departments spoken by the Yuracaré people.
Mataguayo–Guaicuru, Mataco–Guaicuru or Macro-Waikurúan is a proposed language family consisting of the Mataguayan and Guaicuruan languages. Pedro Viegas Barros claims to have demonstrated it. These languages are spoken in Argentina, Brazil, Paraguay, and Bolivia.
Kunza is a mostly extinct language isolate spoken in the Atacama Desert of northern Chile and southern Peru by the Atacama people, who have since shifted to Spanish. The last speaker was documented in 1949; however, it has since been learned that the language is still spoken in the desert.
Candoshi-Shapra is an indigenous American language isolate, spoken by several thousand people in western South America along the Chapuli, Huitoyacu, Pastaza, and Morona river valleys. There are two dialects, Chapara and Kandoashi (Kandozi). It is an official language of Peru, like other native languages in the areas in which they are spoken and are the predominant language in use. Around 88.5 percent of the speakers are bilingual with Spanish. The literacy rate in Candoshi-Shapra is 10 to 30 percent and 15 to 25 percent in the second language Spanish. There is a Candoshi-Shapra dictionary, and grammar rules have been codified.
Leco, also written as Leko, is a language isolate that, though long reported to be extinct, is spoken by 20–40 individuals in areas east of Lake Titicaca, Bolivia. The Leco ethnic population was 13,527 in 2012.
Andaqui is an extinct language from the southern highlands of Colombia. It has been linked to the Paezan or Barbacoan languages, but no connections have been demonstrated. It was spoken by the Andaqui people of Colombia.
Culle, also spelled Culli, Cullí, or Kulyi, is a poorly attested extinct language of the Andean highlands of northern Peru. It is the original language of the highlands of La Libertad Region, the south of the Cajamarca Region (Cajabamba), and the north of the Ancash region. It is known through various word lists collected while the language was still spoken and through vocabulary loaned into the Spanish spoken in the region.
Quechumaran or Kechumaran is a language-family proposal that unites Quechua and Aymara. Quechuan languages, especially those of the south, share a large amount of vocabulary with Aymara. The hypothesis of the existence of Quechuamara was originally posted by linguist Norman McQuown in 1955. Terrence Kaufman finds the proposal reasonably convincing, but Willem Adelaar, a Quechua specialist, believes the similarities to be caused by borrowing during long-term contact. Lyle Campbell suspects that the proposal is valid but does not consider it to have been conclusively proved.
The Tiniwan languages are two extinct and one moribund language of Colombia that form a small family.
Chimané (Tsimane') is a South American language isolate. Some dialects are known as Mosetén. Chimane is a language of the western Bolivian lowlands spoken by the Tsimane peoples along the Beni River and the region around San Borja in the Department of Beni (Bolivia). Sakel (2004) classifies them as two languages for a number of reasons, yet some of the variants of the language are mutually intelligible and they reportedly have no trouble communicating and were evidently a single language separated recently through cultural contact.
The Timotean languages were spoken in the Venezuelan Andes around what is now Mérida. It is assumed that they are extinct. However, Timote may survive in the so-far unattested Mutú (Loco) language, as this occupies a mountain village (Mutús) within the old Timote state.
Lapachu, also known as Apolista or Aguachile, is an extinct Arawakan language of Bolivia. Aikhenvald (1999) classifies it together with Terena, Moxos, and related languages. It is not clear from surviving descriptions whether it was one language or two.
Harákmbut–Katukinan is a proposal linking the South American indigenous language families Harákmbut and Katukinan. There is reasonably good evidence that the two are related. Jolkesky (2011) also adds Arawan to the family.
Andoque–Urequena is a language family that consists of a pair of languages, Andoque and Urequena. The close relationship of Urequena to Andoque was first recognized by Marcelo Jolkesky.
