Language revitalization is when people work together to help bring back a language that is used less and less. This usually happens when a language used to be used by a lot of people, but now much fewer people speak it. Language revitalization is when people try to make it easier for people to learn and use the language again. They may do this by getting people to talk about it, or by teaching it in schools, or by creating things like books and movies in the language.
