Ticuna language
Ticuna, or Tikuna, is a language spoken by approximately 40,000 people in Brazil, Peru, and Colombia. It is the native language of the Ticuna people. Ticuna is generally classified as a language isolate, but may be related to the extinct Yuri language. (See Tïcuna-Yuri.) It is a tonal language, and therefore the meaning of words with the same phonemes can vary greatly simply by changing the tone used to pronounce them.
Tïcuna is also known as Magta, Maguta, Tucuna/Tukuna, and Tukna.
Sociolinguistic situation
Brazil
Despite being home to more than 50% of the Ticunas, Brazil has only recently started to invest in native language education. Brazilian Ticunas now have a written literature and an education provided by the Brazilian National Foundation for the Indian (FUNAI) and the Ministry of Education. Textbooks in Ticuna are used by native teachers trained in both Portuguese and Ticuna to teach the language to the children. A large scale project has been recording traditional narrations and writing them down to provide the literate Ticunas with some literature to practice with.
