List of endangered languages in India
An endangered language is a language that is at a 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" (not endangered) and "extinct":
 Vulnerable
 Definitely endangered
 Severely endangered
 Critically endangered
