According to Ethnologue, there are 6,912 languages in the world. Lots of these are at risk of being lost. It is estimated that one “disappears” every two weeks as the last person who can speak the language dies.
The Living Tongue Institute for Endangered Languages is rapidly trying to capture and document them before they disappear.
As people in remote geographies die off and the next generation speaks a new language (to talk with others), the old languages die.
I don’t understand why language disappear because people don’t speak or what?
