India has the world's second highest number of languages.
At present, Indians speak in 780 different languages.
However, 183 of these languages are in different degrees of endangerment.
An endangered language is at a risk of falling out of use as its speakers die out or shift speaking to another language.
To determine the language as endangered, UNESCO (United Nations Educational, Scientific and Cultural organization) outlines 9 factors.
1. Intergenerational language transmission
2. Absolute number of speakers
3. Proportion of speakers existing within the total (global) population
4. Language use within existing contexts and domains
5. Response to language use in new domains and media
6. Availability of materials for language education and literacy
7. Government and institutional language policies
8. Community attitudes toward their language
9. Amount and quality of documentation
