There were a total of about 6,000 languages worldwide in the 2000s. Most of these are small languages on the verge of extinction; An estimate released in 2004 stated that by 2050, about 90% of the languages currently spoken will be extinct.
In the modern era, languages have generally become extinct as a result of cultural aggression, especially in European countries where local languages are being gradually abandoned due to lingua franca.
There are two types of lost languages. Extinct language and dead language. Extinct languages mean languages that currently have no speakers. Dead language, on the other hand, is a language that is not a local language of a community but is still used in various fields, such as Latin.
