American Indian languages

Indigenous languages of the Americas are spoken by indigenous peoples from Alaska and Greenland to the southern tip of South America, encompassing the land masses that constitute the Americas. These indigenous languages consist of dozens of distinct language families, as well as many language isolates and unclassified languages.

Many proposals to group these into higher-level families have been made, such as Joseph Greenberg's Amerind hypothesis. This scheme is rejected by nearly all specialists.

According to UNESCO, most of the indigenous American languages in North America are critically endangered, and many are already extinct. The most widely spoken indigenous language is Southern Quechua, with about 6 to 7 million speakers, primarily in South America.

Thousands of languages were spoken by various peoples in North and South America prior to their first contact with Europeans. These encounters occurred between the beginning of the 11th century (with the Nordic settlement of Greenland and failed efforts in Newfoundland and Labrador) and the end of the 15th century (the voyages of Christopher Columbus). Several indigenous cultures of the Americas had also developed their own writing systems, the best known being the Maya script. The indigenous languages of the Americas had widely varying demographics, from the Quechuan languages, Aymara, Guarani, and Nahuatl, which had millions of active speakers, to many languages with only several hundred speakers. After pre-Columbian times, several indigenous creole languages developed in the Americas, based on European, indigenous and African languages.
