List of endangered languages in Brazil
An endangered language is a language that it is at risk of falling out of use, generally because it has few surviving speakers. If it loses all of its native speakers, it becomes an extinct language. UNESCO defines four levels of language endangerment between "safe" and "extinct":
- Vulnerable
- Definitely endangered
- Severely endangered
- Critically endangered
