* No Definitive List: There's no single, universally agreed-upon authority that maintains a comprehensive list of all languages.
* Fluid and Changing: Languages evolve, die out, and emerge. New dialects and languages are constantly developing.
* Defining a Language: The very definition of a "language" can be subjective. Some might consider distinct dialects to be separate languages, while others might categorize them as variations of a single language.
However, I can provide you with some resources that can help you explore this topic further:
* Ethnologue: This is a widely respected resource that catalogs languages worldwide. [https://www.ethnologue.com/](https://www.ethnologue.com/)
* Wikipedia List of Languages by Family: Wikipedia offers a categorized list of language families and branches. [https://en.wikipedia.org/wiki/List_of_language_families](https://en.wikipedia.org/wiki/List_of_language_families)
* UNESCO Atlas of the World's Languages in Danger: This resource highlights languages that are endangered or at risk of extinction. [https://www.unesco.org/en/articles/unesco-atlas-worlds-languages-danger](https://www.unesco.org/en/articles/unesco-atlas-worlds-languages-danger)
Remember that these resources are not exhaustive, but they provide a good starting point for your exploration.
