Patagonia refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south.
The Chonan languages are a family of indigenous American languages which were spoken in Tierra del Fuego and Patagonia. Two Chon languages are well attested: Selk'nam, spoken by the people of the same name who occupied territory in the northeast of Tierra del Fuego; and Tehuelche spoken by the people of the same name who occupied territory north of Tierra del Fuego. The name 'Chon', or Tshon, is a blend of 'Tehuelche' and 'Ona'.
The Gününa küna, or sometimes, Puelche are indigenous peoples living east of the Andes Mountains in Chile and Southwest Argentina. They spoke the Puelche language. The name "Puelche" was not native, but was given to them by the Mapuche. They were annihilated by plagues and epidemics in the late 18th century, with survivors merging into other groups such as the Mapuche, Het, and Tehuelche.
Guaicuruan is a language family spoken in northern Argentina, western Paraguay, and Brazil. The speakers of the languages are often collectively called the Guaycuru peoples. For the most part, the Guaycuruans lived in the Gran Chaco and were nomadic and warlike, until finally subdued by the various countries of the region in the 19th century.
Páez is a language of Colombia, spoken by the Páez people. Crevels (2011) estimates 60,000 speakers out of an ethnic population of 140,000.
Cueva is a poorly attested and often misclassified extinct indigenous language of Panama. The Cueva people were exterminated between 1510 and 1535 during Spanish colonization. During the 17th and 18th centuries the Kuna repopulated the Cueva area.
The Tehuelche people, also called the Aónikenk, are an indigenous people from eastern Patagonia in South America. In the 18th and 19th centuries the Tehuelche were influenced by Mapuche people, and many adopted a horseriding lifestyle. Once a nomadic people the lands of the Tehuelche were colonized in the 19th century by Argentina and Chile gradually disrupting their traditional economies. The establishment of large sheep farming estates in Patagonia was particularly detrimental to the Tehuelche. Contact with outsiders also brought in infectious diseases ushering deadly epidemics among Tehuelche tribes. Most existing members of the group currently reside the in cities and towns of Argentine Patagonia.
Chimuan or Yuncan is a hypothetical small extinct language family of northern Peru and Ecuador.
Puelche was a language formerly spoken by the Puelche people in the Pampas region of Argentina. The language is also known as Gününa Küne, Gennaken (Guenaken), Northern Tehuelche, Gününa Yajich, Ranquelche, and Pampa.
Tehuelche is one of the Chonan languages of Patagonia. Its speakers were nomadic hunters who occupied territory in present-day Chile, north of Tierra del Fuego and south of the Mapuche people. It is also known as Aonikenk or Aonekko 'a'ien.
Witoto, or Huitoto, is an indigenous American language or language family spoken in Colombia and Peru.
The Fuegian languages are the indigenous languages historically spoken in Tierra del Fuego by Native Americans. Adelaar lists the Fuegian languages as the Kawésqar language, the Ona language and the Yaghan language in addition to Chono, Gününa Yajich, and the Tehuelche language.
The Moluche or Nguluche are an indigenous people of Chile. Their language was a dialect of Mapudungun, a Mapuche language. At the beginning of the Conquest of Chile by the Spanish Empire the Moluche lived in what came to be known as Araucanía. The Moluche were called Araucanos ("Araucanians") by the Spanish.
Coconuco, also known as Guambiano and Misak, is a dialect cluster of Colombia spoken by the Guambiano indigenous people. Though the three varieties, Guambiano, moribund Totoró, and the extinct Coconuco are traditionally called languages, Adelaar & Muysken (2004) believe that they are best treated as a single language.
The Teushen language is an indigenous language of Argentina, which may be extinct. It was spoken by the Teushen people, a nomadic hunter-gatherer people of Patagonia, who lived between the Puelche people to their north and the Tehuelche people to the south, who occupied the central part of the Tierra del Fuego region. The tribe is now extinct.
Timote, also known as Cuica or Timote–Cuica, is the language of the Timote–Cuica state in the Venezuelan Andes, around the present city of Mérida and south of Lake Maracaibo.
Mucuchí (Mokochi) is a suspected Timotean language of Venezuela. Mirripú (Maripú) was a dialect. Most classifications place them as dialects of Timote, with Cuica being a separate language, but the data in Loukotka indicates that Timote and Cuica were one language, and Mucuchí–Marripú another; this is reflected in Campbell (2012).
The Marañón River basin, at a low point in the Andes which made it an attractive location for trade between the Inca Empire and the Amazon basin, once harbored numerous languages which have been poorly attested or not attested at all. Those of the middle reaches of the river, above the Amazon basin, were replaced in historical times by Aguaruna, a Jivaroan language from the Amazon which is still spoken there. The languages further upriver are difficult to identify, due to lack of data. The region was multilingual at the time of the Conquest, and the people largely switched to Spanish rather than to Quechua, though Quechua also expanded during Colonial times.
The Haush language was an indigenous language spoken by the Haush people and was formerly spoken on the island of Tierra del Fuego. The Haush were considered the oldest inhabitants of Tierra del Fuego; they inhabited the far eastern tip of the Mitre Peninsula. They made regular hunting trips to Isla de los Estados.
Teushentherium is an extinct genus of notohippid notoungulate from the Oligocene of Argentina. Fossils have been found in the Sarmiento Formation of Argentina.
