query: What are the characteristics of the Tuparí language?
answer: Tuparí is a critically endangered indigenous language of Brazil belonging to the Tupian language family.  It has a complex morphology and morphosyntax, including a nominal domain with marked aspects, verbal morphology with evidentiality marking, and valency manipulation prefixes.  It also features a four-case system (nuclear, locative, instrumental-lative, oblique), with the possibility of case stacking. Quantification is expressed through verbal morphemes rather than noun phrase modification.
