1 18 The Amazon Alexandra Y. Aikhenvald 1 Lowland Amazonian languages: a backdrop The Amazon basin is an area of high linguistic diversity (rivalled only by the island of New Guinea). It comprises around 350 languages grouped into over fifteen language families, in addition to a number of isolates. The six major linguistic families of the Amazon basin are: • The Arawak language family is the largest in South America in terms of its geographical spread, with over forty extant languages between the Caribbean and Argentina. Well- established subgroups include Campa in Peru and a few small North Arawak groupings in Brazil and Venezuela. Arawak languages are spoken in at least ten locations north of the River Amazon, and in at least ten south of it. European languages contain a number of loans from Arawak languages, among them hammock and tobacco. • The Tupí language family consists of about seventy languages; nine of its ten branches are spoken exclusively in Amazonia. The largest branch, Tupí-Guaraní, extends beyond the Amazonian Basin into Bolivia and Paraguay. Loans from Tupí-Guaraní languages include jaguar and jacaranda. • Carib languages number about twenty five, and are spoken in various locations in Brazil and Venezuela in northern Amazonia, and in the region of the Upper Xingu and adjacent areas of Mato Grosso in Brazil south of the River Amazon. The place name 'Caribbean' and the noun cannibal (a version of the ethnonym 'Carib') are a legacy from Carib languages. • Panoan languages number about thirty, and are spoken on the eastern side of the Andes in Peru and adjacent areas of Brazil. • The Tucanoan language family spans Brazil, Colombia, Ecuador and north-eastern Peru, with a total number of about twenty languages.
