Here's why it's tricky:
* Dialects vs. Languages: The line between a dialect and a language can be blurry. Some linguists might consider a distinct dialect to be its own language, while others might categorize it as a variation of a broader language.
* Endangered Languages: Many languages are spoken by small numbers of people and are facing extinction. It can be difficult to track how many of these languages exist and how many are disappearing.
* New Languages: Languages are constantly evolving and new varieties are emerging.
Estimates:
* UNESCO: Estimates around 7,100 languages worldwide.
* Ethnologue: Lists over 7,100 languages, but acknowledges that the number is constantly changing.
In conclusion, while there's no exact answer, there are thousands of languages spoken around the world, and the number is constantly fluctuating.
