However, estimates vary widely. Here's a breakdown:
* UNESCO: Estimates around 7,100 languages
* Ethnologue: Lists over 7,100 languages, but acknowledges that many are endangered or nearly extinct.
* Other sources: Some estimates go as high as 10,000 or more.
The reason for this discrepancy is that language is a spectrum, with dialects and regional variations blurring the lines between distinct languages.
It's important to remember that:
* Endangered languages: Many languages are at risk of extinction, making it difficult to track their number accurately.
* Dialects vs. languages: The distinction between a dialect and a language can be subjective.
* New languages: New languages are constantly emerging as a result of globalization and language contact.
So, while we can offer estimates, the exact number of languages in the world remains a complex and constantly evolving question.
