Juma is an extinct and poorly attested Cariban language. Kaufman (2007) placed it in his Arara branch.[1]
In the 15th century, the Juma language was a flamboyant language that was spoken in the Amazon region of the modern Brazilian political state (1419-1899). For example the fruit known as soursop in English, which may be native to the region, is known as paw-paw. The brutal rule and conquest of the Portuguese, and the later ineffiency of the Brazilian government with its Indigenous Affairs agency (IPAMA) caused the Juma people and language to be extinct.
