Arawakan (Arahuacan, Maipuran Arawakan, "mainstream" Arawakan, Arawakan proper), also known as Maipurean (also Maipuran, Maipureano, Maipúre), is a language family that developed among ancient indigenous peoples in South America. Branches migrated to Central America and the Greater Antilles in the Caribbean and the Atlantic, including what is now the Bahamas. Almost all present-day South American countries are known to have been home to speakers of Arawakan languages, the exceptions being Ecuador, Uruguay, and Chile. Maipurean may be related to other language families in a hypothetical Macro-Arawakan stock.
The name Maipure was given to the family by Filippo S. Gilij in 1782, after the Maipure language of Venezuela, which he used as a basis of his comparisons. It was renamed after the culturally more important Arawak language a century later. The term Arawak took over, until its use was extended by North American scholars to the broader Macro-Arawakan proposal. At that time, the name Maipurean was resurrected for the core family. See Arawakan vs Maipurean for details.
The Arawakan linguistic matrix hypothesis (ALMH) suggests that the modern diversity of the Arawakan language family stems from the diversification of a trade language or lingua franca that was spoken throughout much of tropical lowland South America. Proponents of this hypothesis include Santos-Granero (2002) and Eriksen (2014). Eriksen (2014) proposes that the Arawakan family had only broken up after 600 CE, but Michael (2020) considers this to be unlikely, noting that Arawakan internal diversity is greater than that of the Romance languages. On the other hand, Blench (2015) suggests a demographic expansion that had taken place over a few thousand years, similar to the dispersals of the Austronesian and Austroasiatic language families in Southeast Asia.
As one of the most geographically widespread language families in all of the Americas, Arawakan linguistic influence can be found in many language families of South America.
