Concept
Over a thousand indigenous languages are spoken by the Indigenous peoples of the Americas. These languages cannot all be demonstrated to be related to each other and are classified into a hundred or so language families (including a large number of language isolates), as well as a number of extinct languages that are unclassified because of a lack of data. Many proposals have been made to relate some or all of these languages to each other, with varying degrees of success. The most widely reported is Joseph Greenberg's Amerind hypothesis, which, however, nearly all specialists reject because of severe methodological flaws; spurious data; and a failure to distinguish cognation, contact, and coincidence. According to UNESCO, most of the Indigenous languages of the Americas are critically endangered, and many are dormant (without native speakers but with a community of heritage-language users) or entirely extinct. The most widely spoken Indigenous languages are Southern Quechua (spoken primarily in southern Peru and Bolivia) and Guarani (centered in Paraguay, where it shares national language status with Spanish), with perhaps six or seven million speakers apiece (including many of European descent in the case of Guarani). Only half a dozen others have more than a million speakers; these are Aymara of Bolivia and Nahuatl of Mexico, with almost two million each; the Mayan languages Kekchi, Quiché, and Yucatec of Guatemala and Mexico, with about 1 million apiece; and perhaps one or two additional Quechuan languages in Peru and Ecuador. In the United States, 372,000 people reported speaking an Indigenous language at home in the 2010 census, and similarly in Canada, 133,000 people reported speaking an Indigenous language at home in the 2011 census. In Greenland, about 90% of the population speaks Greenlandic, the most widely spoken Eskimo–Aleut language. Over a thousand known languages were spoken by various peoples in North and South America prior to their first contact with Europeans.
